[PATCH 2/5] arm64: dts: qcom: sa8540p: use sa8540p gpucc compatible

[Johan Hovold]

The SA8540P platform is closely related to SC8280XP but differs in that
it uses an external supply for the GX power domain.

Use the new SA8540P compatible string for the GPU clock controller so
that the OS can determine which resources to look for.

Note that a fallback SC8280XP compatible is added temporarily to avoid
any temporary regressions for sa8295p-adp.

Fixes: fd5821a1a83c ("arm64: dts: qcom: sa8540p: Drop gfx.lvl as power-domain for gpucc")
