[PATCH RFC 05/24] dt-bindings: clock: qcom,gpucc: Sort out SA8540P constraints

[Konrad Dybcio]

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.

Signed-off-by: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>
