Subject: [PATCH 0211/1795] pinctrl: sh-pfc: Drop width parameter of
sh_pfc_{read,write}_reg()
On modern Renesas SoCs, all PFC registers are 32-bit, and all callers of
sh_pfc_{read,write}_reg() already operate on 32-bit registers only.
Hence make the 32-bit width implicit, and rename the functions to
sh_pfc_{read,write}() to shorten lines.
All accesses to 8-bit or 16-bit registers are still done using
sh_pfc_{read,write}_raw_reg().
