THis patchset adds support for SC8280XP SoC machine driver.
First patch moves some of the commonly used code to common from sm8250 machine driver
and the follow on code adds minimal support for sc8280xp.
Currently this driver is only tested with SmartSpeakers and Headset
on Lenovo Thinkpad X13s.
Support for sm8450 is tested and I will post the patches soon.
Thanks,
Srini
