[0/4] soc: rockchip: power-domain: Add regulator support

This series adds the possibility to add supplies to the rockchip power
domains. This is a bit more complicated then it should be as we can
get a regulator from a device node only when a device is attached to
it, so this series starts by moving the power domains into a device.
Overall this series makes the clock handling nicer because we no longer
have to use of_clk_get(), but can use a plain devm_clk_bulk_get_all()
to retrieve the domain clocks.

All this is needed for the RK3568-EVB board where the power domain of
the GPU is supplied by an external regulator.
