ASoC: cs35l45: Analog PCM Volume and Amplifier Mode controls
Adds "Analog PCM Volume" control with supported values
0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB.
The amplifier can operate either in Speaker Mode or Receiver Mode
as configured by the user. Speaker Mode has four gain options
to support maximum amplifier output amplitude for loud
speaker application. Receiver Mode has further optimized
noise performance while maintaining sufficient output to support
phone receiver application. While configured in Receiver Mode,
the analog PCM Volume control is disabled and
the analog gain is fixed to 1dB.

ASoC: cs35l45: Update to use maple tree register cache
The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

Update the cs35l45 driver to use the more modern data structure.

ASoC: cs35l45: Hibernation support
Adds support for a low-power Hibernation State.
Add support for a low-power hibernation state for the DSP. In
this state the DSP RAM contents are maintained, such that
firmware does not need to be re-downloaded, but the rest of the
chip's register state is lost.
Entry to this state is achieved via the register interface
(either by an external driver using the control port, or the
programmable DSP). Exit from this state is triggered by activity
on device GPIO pins, intended SPI transaction, or I2C
transaction with intended slave address.

Now tables isn't a separate module, definitely no need to have a

ASoC: cs35l45: Remove separate tables module
There is no reason to have a separate module for the tables file it just
holds regmap callbacks and register patches used by the main part of the
driver. Remove the separate module and merge it into the main driver
module.
