[PATCH 0/2] MT8195 Cherry: Assign MFG vregs for power saving

[AngeloGioacchino Del Regno]

This series assigns the right regulators to MFG0 and MFG1, respectively
VGPU (GPU Core) and VSRAM_OTHERS (GPU SRAM), and removes the property
regulator-always-on from both.

This allows to save power both during runtime suspend and during system
sleep; specifically because:
 1. The GPU SRAM regulator is switched off during runtime suspend
 2. The GPU Core regulator is switched off during system sleep

Of course, in order for those power saving actions to actually take
place, it is required to also have the code in [1].
Anyway, even without series [1], this will not introduce any unstability
as the Vgpu regulator will simply not ever get turned off.
