pinctrl: renesas: rzg2l: Fix save/restore of {IOLH,IEN,PUPD,SMT} registers

The rzg2l_pinctrl_pm_setup_regs() handles save/restore of
{IOLH,IEN,PUPD,SMT} registers during s2ram, but only for ports where all
pins share the same pincfg. Extend the code to also support ports with
variable pincfg per pin, so that {IOLH,IEN,PUPD,SMT} registers are
correctly saved and restored for all pins.
