ASoC: wm_adsp: Add support for "toggle" preloaders
In the case a device can support retaining the firmware memory across
low power states it is useful for the preloader widget to only power up
whilst actually loading/unloading the core, as opposed to the normal
operation where the widget is powered for the entire time a firmware is
preloaded onto the core. Add support for this mode and a flag to enable
it.

firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPs
wm_adsp originally provided firmware loading on some audio DSP and was
implemented as an ASoC codec driver. However, the firmware loading now
covers a wider range of DSP cores and peripherals containing them,
beyond just audio. So it needs to be available to non-audio drivers. All
the core firmware loading support has been moved into a new driver
cs_dsp, leaving only the ASoC-specific parts in wm_adsp.

ASoC: wm_adsp: Switch to using wm_coeff_read_ctrl for compressed buffers
When parsing a compressed buffer from the firmware the driver currently
open codes reading the firmware coefficient containing the buffer
description. Improve this slightly by using the coefficient read
functions already provided by the wm_adsp driver. It is worth noting
this change requires the running variable to be set before
wm_adsp_buffer_init is called, however this is safe, since its all still
under the power lock and nothing in the compressed code gates itself on
running.

ASoC: wm_adsp: Put debugfs_remove_recursive back in
This patch reverts commit acbf58e53041 ("ASoC: wm_adsp: Let
soc_cleanup_component_debugfs remove debugfs"), and adds an
alternate solution to the issue. That patch removes the call to
debugfs_remove_recursive, which cleans up the DSPs debugfs. The
intention was to avoid an unbinding issue on an out of tree
driver/platform.

The issue with the patch is it means the driver no longer cleans up
its own debugfs, instead relying on ASoC to remove recurive on the
parent debugfs node. This is conceptually rather unclean, but also it
would prevent DSPs being added/removed independently of ASoC and soon
we are going to be upstreaming some non-audio parts with these DSPs,
which will require this.

Finally, it seems the issue on the platform is a result of the
wm_adsp2_cleanup_debugfs getting called twice. This is very likely a
problem on the platform side and will be resolved there. But in the mean
time make the code a little more robust to such issues, and again
conceptually a bit nicer, but clearing the debugfs_root variable in the
DSP structure when the debugfs is removed.

ASoC: wm_adsp: Fix uninitialized variable warnings
wm_adsp_read_data_word() used if (ret) to check for an error from
wm_adsp_read_raw_data_block(). While this is perfectly valid,
wm_adsp_read_raw_data_block() itself uses if (ret < 0) and three
calls to wm_adsp_read_data_word() also use if (ret < 0).

This creates an error check chain like this:

  1st) if (ret < 0) return ret;
  2nd) if (ret) return ret;
  3rd) if (ret < 0) ...

This can confuse the compiler into thinking that there are possible
returns > 0 from the middle if() that are not handled by the final
if(). If this was true it would lead to using uninitialized variables
later in the outer function.

Fix this by changing the test in wm_adsp_read_data_word() to be
if (ret < 0).

ASoC: wm_adsp: Only use __be32 for big-endian data
This fixes some minor cases where u32 or unsigned int types were used
to store big-endian data, and __be32 types used to store both big-endian
and cpu-endian data. This was producing sparse warnings.

Most cases resulted from using the same variable to hold the big-endian
value and its converted cpu-endian value. These can be simply fixed by
introducing another local variable, or avoiding storing the intermediate
value back into the original variable.

One special case is the raw_buf used in the compressed streams to transfer
data from DSP to user-side. The endian conversion happens in-place (as
there's no point introducing another buffer) so a cast to (__be32 *) is
added when passing it to wm_adsp_read_raw_data_block().

ASoC: wm_adsp: Improve handling of raw byte streams
As the register map is 16-bit or 32-bit big-endian, the 24-bit
DSP words appear padded and with the bytes swapped. When reading a
raw stream of bytes, the pad bytes must be removed and the data bytes
swapped back to their original order.

The previous implementation of this assumed that the be32_to_cpu() in
wm_adsp_read_data_block() would swap back to little-endian. But this is
obviously only true on a little-endian CPU. It also made two walks
through the data, once to endian-swap and again to strip the pad bytes.

This patch re-works the code so that the endian-swap and unpad are done
together in a single walk, and it is not dependent on the endianness of
the CPU. The data_word_size argument to wm_adsp_remove_padding() has been
dropped because currently this is always 3.

ASoC: wm_adsp: remove "ctl" from list on error in wm_adsp_create_control()
The error handling frees "ctl" but it's still on the "dsp->ctl_list"
list so that could result in a use after free.  Remove it from the list
before returning.

ASoC: wm_adsp: Pass full name to snd_ctl_notify
A call to wm_adsp_write_ctl() could cause a kernel crash if it
does not retrieve a valid kcontrol from snd_soc_card_get_kcontrol().
This can happen due to a missing control name prefix. Then,
snd_ctl_notify() crashes when it tries to use the id field.

Modified wm_adsp_write_ctl() to incorporate the name_prefix (if applicable)
such that it is able to retrieve a valid id field from the kcontrol
once the platform has booted.

ASoC: wm_adsp: Update naming in error handling
It seems the datasheet has never used the word slave for this error
status bit and has always used the term address error. So update the
driver to match the datasheets and also in the process align a bit
better with avoiding the use of such words where possible.

ASoC: wm_adsp: Use scnprintf() for the limited buffer output
snprintf() is a hard-to-use function, it's especially difficult to use
it for concatenating substrings in a buffer with a limited size.
Since snprintf() returns the would-be-output size, not the actual
size, the subsequent use of snprintf() may point to the incorrect
position.

Use scnprintf() instead for fixing such potential errors.

ASoC: wm_adsp: Correct cache handling of new kernel control API
The recently added API that exposes firmware mixer controls to the
kernel is missing cache handling and all writes bypass the cache, this
obviously causes the cache to get out of sync with the hardware. Factor
out the cache handling into two new helper functions and call those from
both the normal ALSA control handlers and the new kernel API.
