ASoC: codecs: qcom add support for SM8450 and SC8280XP

Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

This patchset adds support for SM8450 and SC8280XP SoC and also some of
the fixes requried to get stable audio on X13s.

Tested SmartSpeakers and Headset on SM8450 MTP and
Lenovo Thinkpad X13s.
