Add support for CS42L43B codec to CS42L43 driver

Merge series from Maciej Strozek <mstrozek@opensource.cirrus.com>:

Introducing CS42L43B, a variant of the CS42L43 codec with changes to
PDM (DMIC) inputs, RAM/ROM memory and extra channels to two SoundWire
ports and ISRCs, and can be supported by the existing CS42L43 driver
with some modifications.
