ASoC: Updates for v6.6

Browse Source 
Here's an initial batch of updates for ASoC for this release cycle.
 We've got a bunch of new drivers in here, a bit of core work from
 Morimoto-san and quite a lot of janitorial work.  There's several
 updates that pull in changes from other subsystems in order to build
 on them:
 
  - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
    some IIO changes.
  - Create a library function for intlog10() and use it in the NAU8825
    driver.
  - Include the ASoC tests, including the topology tests, in the default
    KUnit full test coverage.  This also involves enabling UML builds of
    ALSA since that's the default KUnit test environment which pulls in
    the addition of some stubs to the driver.
  - More factoring out from Morimoto-san.
  - Convert a lot of drivers to use the more modern maple tree register
    cache.
  - Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
    CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.
