[PATCH v4 15/16] phy: qcom-qmp-pcie: add support for sc8280xp

[Johan Hovold <johan+linaro@kernel.org>]

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.
