Instantiate always-on power domain for R9A09G011 SoC. At the moment, all
the IPs are part of this domain.

As not all IPs are part of the always-on domain, I'd rather defer this
until all domains are handled in the driver.
Note that RZ/V2M does not have CPG_BUS_*_MSTOP registers,
but uses the Internal Power Domain Controller (PMC).

Gr{oetje,eeting}s,
