Subject: [PATCH 2/4] pmdomain: renesas: rcar-sysc: Split R-Car M3-W and M3-W+ sub-drivers
Currently R-Car M3-W and M3-W+ are handled by a single sub-driver,
but using separate Kconfig symbols and separate rcar_sysc_info
structures, and fixup code to handle the remaining differences.
Prepare for handling more differences by splitting them in two separate
sub-drivers.
