Series phy: qcom-qmp-pcie: add support for sc8280xp | expand

Commit Message

Johan Hovold Oct. 28, 2022, 1:36 p.m. UTC 
Add support for the single and dual-lane PHYs found on SC8280XP.

Note that the SC8280XP binding does not try to describe every register
subregion and instead the driver holds the corresponding offsets.
