soc: renesas: rcar-sysc: Provide helpers to power up/down CPUs
Provide helpers to control CPU power areas from platform code, taking
just a CPU index. This will avoid having to pass full CPU power area
parameter blocks, and thus duplicating information already provided by
SoC-specific SYSC drivers.
This will be used on R-Car H1 only.
Later R-Car generations rely on APMU/RST for CPU power area control.
