[PATCH 2/4] pmdomain: renesas: rcar-sysc: Split R-Car M3-W and M3-W+ sub-drivers

From: Geert Uytterhoeven
Date: Wed Apr 17 2024 - 06:31:19 EST


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.
