From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>
The platform in question is a close cousin of SC8280XP, most notably
lacking an on-SoC VDD_GFX rail, substituting it with an external
regulator.
The GPU_CC block was previously believed to only require a handle to
some form of VDD_GFX, but that's now known not to be enough.
Introduce a new compatible, using the SC8280XP fallback, to constrain
a different number of power-domains and remove the pd-regulator
exclusivity check, as it no longer applies.
