The RK8602 and RK8603 voltage regulators on the Rock 5B board provide
the power lines vdd_cpu_big0 and vdd_cpu_big1, respectively.

Add the necessary device tree nodes and bind them to the corresponding
CPU big core nodes.

I mentioned in the cover letter that the support for the RK860X 
regulators has been recently merged via [1]. The patches in this 
series have been verified on next-20230413.

Yes, according to [1], initially discussed in [2].
