pinctrl: renesas: rzg2l: Fix SMT register cache handling
Store SMT register cache per bank instead of using a single array.
On RZ/V2H(P), RZ/V2N, and RZ/G3E, the SMT register is split across two
32-bit registers: bits 0/8/16/24 control pins 0-3, while pins 4-7 are
controlled by the corresponding bits in the next register. The previous
implementation cached only a single SMT register, leading to incomplete
save/restore of SMT state.
Convert cache->smt to a per-bank array and allocate storage for both
halves. Update suspend/resume handling to save and restore both SMT
registers when present.
Fixes: 837afa592c623 ("pinctrl: renesas: rzg2l: Add suspend/resume support for Schmitt control registers")
