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.
