Add optional support for a voltage supply required to enable a
power domain. The binding follows the way it is handled by the
Mediatek binding to keep things consistent.

This will initially be used by the RK3588 GPU power domain, which
fails to be enabled when the GPU regulator is not enabled.

That we have regulators supplying internal components in the soc
is the case for all Rockchip SoCs, though it looks like thankfully this
hadn't bitten us before.

So having the ability to define those supplies makes a lot of sense
