[PATCH RFC 07/24] arm64: dts: qcom: sa8540p: Describe GPU_CC power plumbing requirements

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

A number of power rails must be powered on in order for GPU_CC to
function. Ensure that's conveyed to the OS.

Fixes: eec51ab2fd6f ("arm64: dts: qcom: sc8280xp: Add GPU related nodes")
