arm64: dts: rockchip: Add missing SFC power-domains to rk3576

Browse Source 
Add the power-domains for the RK3576 SFC nodes according to the
TRM part 1. This fixes potential SErrors when accessing the SFC
registers without other peripherals (e.g. eMMC) doing a prior
power-domain enable. For example this is easy to trigger on the
Rock 4D, which enables the SFC0 interface, but does not enable
the eMMC interface at the moment.
