Note that if this lands after Elaine / Caesar's patch ("arm64: dts:
rockchip: add the power domain node for rk3399")
<https://patchwork.kernel.org/patch/9206415/> then you need to respin
adding powerdomain references here for correctness.

If this lands before Elaine / Caesar's patch then the other patch
needs to be re-spun.  ;)
