Tested-by: Chen-Yu Tsai <wenst at chromium.org>

on MT8183, MT8186, MT8192 and MT8195 Chromebooks.

BTW, Angelo, I see that Panfrost keeps the GPU regulator enabled, but
the power domains, and thus the SRAM regulator, get powered off when
the GPU is not in use. There doesn't seem to be any damaging effects,
but I worry about idle power consumption.
