Due to the different PMIC configuration found in the SA8295P platform, compared to SC8280XP, the VDD_GFX pads are supplied by an dedicated MAX20411 LDO. Support for expressing the regulator supply is added to the binding, the support for enabling the parent supply for GX is added, the missing gfx.lvl power-domain is dropped, and the DeviceTree is wired up to enable the GPU in this configuration.

Sorry, I forgot to change the subject prefix of the rpmhpd patch, and pick up Konrad's two r-b. Regards, Bjorn
--- Changes in v4: - Updated qcom,gpucc.yaml binding check that both power-domains and vdd-gfx-supply isn't used together.
