[PATCH v2 05/10] arm64: dts: rockchip: Add vdd_cpu_big reg to rk3588-edgeble-ncm6

[Jagan Teki]

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.
