Merge series "ASoC: codecs: add support for LPASS Codec macros" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

This patchset adds support for two Codec Macro blocks( WSA and VA) available in
Qualcomm LPASS (Low Power Audio SubSystem).

There are WSA, VA, TX and RX Macros on LPASS IP, each of the Macro block
has specific connectivity like WSA Macros are intended to connect
to WSA Smart speaker codecs via SoundWire. VA Macro is intended for DMICs,
and TX/RX for Analog codecs via SoundWire like other WCD Codecs to provide
headphone/ear/lineout etc ..

Most of the work is derived from downstream Qualcomm kernels.
Credits to various Qualcomm authors from Patrick Lai's team who have
contributed to this code.

This patchset has been tested on support to Qualcomm Robotics RB5 Development
Kit based on QRB5165 Robotics SoC. This board has 2 WSA881X smart speakers
with onboard DMIC connected to internal LPASS codec via WSA  and VA macros
respectively.

Thanks,
srini

-Changes since v2:
 - various unnecessary variable intializations removed, suggested by Pierre
 - fixed a static checker error
 - collected reviews for dt-bindings.
 - fixed licence headers as suggested by Pierre.
