[PATCH v3 3/8] clk: qcom: gpucc-sc8280xp: Add external supply for GX gdsc

[Bjorn Andersson <quic_bjorande@quicinc.com>]

On SA8295P and SA8540P the GFX rail is powered by a dedicated external
regulator, instead of the rpmh-controlled "gfx.lvl".

Define the "vdd-gfx" as the supply regulator for the GDSC, to cause the
gdsc logic to look for, and control, this external power supply.
