Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro. The macro didn't give any better readability.
Along with it, drop the unnecessary assignment before the
snd_dma_alloc_pages() call and simplify by returning the error code
directly.

When a driver needs to deal with a special buffer like a SG or a
vmalloc buffer, it has to set up the PCM page ops explicitly for the
corresponding helper function. This is rather error-prone and many
people forgot or incorrectly used it.
For simplifying the call patterns and avoiding such a potential bug,
this patch enhances the PCM default mmap handler to check the
(pre-)allocated buffer type and handles the page gracefully depending
on the buffer type. If the PCM page ops is given, the ops is still
used in a higher priority. The new code path is only for the default
(NULL page ops) case.

This patch adds the vmalloc buffer support to ALSA memalloc core. A
new type, SNDRV_DMA_TYPE_VMALLOC was added.
The vmalloc buffer has been already supported in the PCM via a few own
helper functions, but the user sometimes get confused and misuse
them. With this patch, the whole buffer management is integrated into
the memalloc core, so they can be used in a sole common way.

Currently we pass the artificial device pointer to the allocation
helper in the case of SNDRV_DMA_TYPE_CONTINUOUS for passing the GFP
flags. But all common cases are the allocations with GFP_KERNEL, and
it's messy to put this in each place.
In this patch, the memalloc core helper is changed to accept the NULL
device pointer and it treats as the default mode, GFP_KERNEL, so that
all callers can omit the complex argument but just leave NULL.

Since we apply the own mutex (bus->cmd_mutex) in HDA core side, the
internal locking in regmap is superfluous. This patch adds the flag
to indicate that.
Also, an infamous side-effect by this change is that it disables the
regmap debugfs, too, and this is seen rather good; the regmap debugfs
isn't quite useful for HD-audio as it provides the very sparse
registers and its debugfs access tends to lead to the way too high
resource usages or sometimes hang up. So it'd be rather safe to
disable it altogether.

The check for the mmap support via hw_support_mmap() function misses
the case where the device is with SNDRV_DMA_TYPE_DEV_UC, which should
have been treated equally as SNDRV_DMA_TYPE_DEV. Let's fix it.
Note that this bug doesn't hit any practical problem, because
SNDRV_DMA_TYPE_DEV_UC is used only for x86-specific drivers
(snd-hda-intel and snd-intel8x0) for the specific platforms that need
the non-cached buffers. And, on such platforms, hw_support_mmap()
already returns true in anyway. That's the reason I didn't put
Cc-to-stable mark here. This is only for any theoretical future
extension.

Originally BeBeB ASICs and firmware supports clock mode to synchronizing
to syt field of received isoc packet. This mode is known as 'SYT Match'
slightly described in IEC 61883-6 (but no detail mechanisms). In this
mode, drivers can control sampling clock in device. Driver for Windows
and macOS uses this feature to perform synchronization for devices
on the same bus.
In this mode, a plug of Music subunit for synchronization is connected
to a plug of isoc unit for incoming packet streaming, then the order to
establish connections is INPUT_PLUG first, OUTPUT_PLUG second.
This commit implements the above.
Actually each device works with its own clock for sampling, therefore
the original design is hardly implemented to vendor's products.

As long as I investigated, there's some cases about the delay for device
between establishing OUTPUT_PLUG and transmitting first isoc packet. For
devices which support BeBoB protocol version 1 can transmit the packet
within several hundred milliseconds, while for devices which support
BeBoB protocol version 3 can transmit the packet within 2 seconds.
Devices with protocol version 1:
* Edirol FA-66
* Yamaha GO46
* Terratec Phase x24 FW
* M-Audio FireWire AudioPhile
* M-Audio FireWire Solo
* M-Audio FireWire 1814
* M-Audio FireWire 410
* Focusrite Saffire Pro 26 I/O
Devices with protocol version 3:
* M-Audio Profire Lightbridge
* Behringer FCA610
* Phonic Firefly 202
At present ALSA bebob driver postpones starting IR context during
1.5 sec for all of supported devices. The delay is too long for
devices with protocol version 1, while it's not enough for devices with
protocol version 3.
This commit improves the delay for these protocols.

As long as I investigated, some devices with BeBoB protocol version 1
can be freezed during several hundreds milliseconds after breaking
connections. When accessing during the freezed time, any transaction
is corrupted. In the worst case, the device is going to reboot.
I can see this issue in:
* Roland FA-66
* M-Audio FireWire Solo
This commit expands sleep just after breaking connections to avoid
the freezed time as much as possible. I note that the freeze/reboot
behaviour is similar to below models:
* Focusrite Saffire Pro 10 I/O
* Focusrite Saffire Pro 26 I/O
The above models certainly reboot after breaking connections.
