[PATCH v17 2/3] pmdomain: rockchip: manage the RK3576 NPU domain supply

[Jiaxing Hu <gahing@gahingwoo.com>]

rockchip_pd_regulator_enable() only reads domain-supply for a domain
marked need_regulator, and the RK3576 NPU power domain is not marked. A
board that sets domain-supply on pd_npu therefore still has to keep
vdd_npu_s0 always on.

Use DOMAIN_RK3576_R for PD_NPU, as for the GPU domain, so the NPU rail is
switched on and off with the domain. This needs the previous patch, or
boards that leave the NPU disabled hang when the unused rail is turned
off.

Tested on a Radxa ROCK 4D without regulator-always-on on vdd_npu_s0: the
rail is off while the NPU is idle and on while it runs.
