ASoC: cs42xx8: 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 cs42xx8 driver to use the more modern data structure.

ASoC: cs42xx8-i2c.c: add module device table for of

When trying to connect the device with the driver through
device-tree it is not working. The of_device_id is defined in
cs42xx8.c but is not correctly included in cs42xx8-i2c.c.

Move of_device_id table to cs42xx8-i2c.c. Get cs42xx8_driver_data
in cs42xx8_i2c_probe() and pass as argument to cs42xx8_probe(). Move
error check if no driver data found to cs42xx8_i2c_probe().

ASoC: cs42xx8: Fix MFREQ selection issue for async mode

When sample rate of TX is different with sample rate of RX in
async mode, the MFreq selection will be wrong.

For example, sysclk = 24.576MHz, TX rate = 96000Hz, RX rate = 48000Hz.
Then ratio of TX = 256, ratio of RX = 512, For MFreq is shared by TX
and RX instance, the correct value of MFreq is 2 for both TX and RX.

But original method will cause MFreq = 0 for TX, MFreq = 2 for RX.
If TX is started after RX, RX will be impacted, RX work abnormal with
MFreq = 0.

This patch is to select proper MFreq value according to TX rate and
RX rate.

ASoC: cs42xx8: Mark chip ID as volatile and remove cache bypass

Rather than manually enabling cache bypass when reading the ID registers
simply remove the default which will cause the first read to go to the
hardware. The old code worked this is simply the more standard way to
implement this. There is a comment included in the code that claims the
chip ID register also contains the right input volume, however this is
clearly not the case from the rest of the driver. Further investigation
reveals exactly the same comment in the wm8962 driver, where this is the
case, so this is almost certainly a copy and paste error from when the
driver was created.
