ASoC: Initial support for Cirrus Logic CS35L56

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

The CS35L56 is a high-performance boosted mono audio amplifier.
Supported control interfaces are I2C, SPI or SoundWire.
Supported audio interfaces are I2S/TDM or SoundWire.

The CS35L56 has a self-booting firmware in ROM, with the ability
to patch the firmware and/or apply tunings.
Patches #1 to #7 add support to cs_dsp and wm_adsp for self-booting
firmware and the ability to apply a .bin file without having to
apply a .wmfw.
