Subject: [PATCH v2 1/2] arm64: select ROCKCHIP_PM_DOMAINS with ARCH_ROCKCHIP

On rk3399 based rockpi4b, mounting rootfs from mmc fails unless
ROCKCHIP_PM_DOMAINS is enabled. Accoriding to
Heiko Stübner <heiko@...ech.de> all SoCs since 2012 have power
domains so the support should be enabled by default.

Failing boot without CONFIG_ROCKCHIP_PM_DOMAINS=y:
