ASoC: codecs: wsa88xx: add support for static port
Merge series from srinivas.kandagatla@linaro.org:
Existing way of allocating soundwire master ports on Qualcommm platforms is
dynamic, and in linear order starting from 1 to MAX_PORTS.
This will work as long as soundwire device ports are 1:1 mapped
linearly. However on most Qcom SoCs like SM8550, SM8650, x1e80100, these
are NOT mapped in that order.
The result of this is that only one speaker among the pair of speakers
is always silent, With recent changes for WSA codec to support codec
versions and along with these patches we are able to get all speakers
working on these SoCs.
