pinctrl: renesas: rzg2l: Add function pointers for OEN register access

Browse source

Introduce function pointers oen_read() and oen_write(), in the struct
rzg2l_pinctrl_data to facilitate reading and writing to the PFC_OEN
register.  On the RZ/V2H(P) SoC, unlocking the PWPR.REGWE_B bit before
writing to the PFC_OEN register is necessary, and the PFC_OEN register
has more bits compared to the RZ/G2L family.  To handle these
differences between RZ/G2L and RZ/V2H(P) and to reuse the existing code
for RZ/V2H(P), these function pointers are introduced.

Additionally, populate these function pointers with appropriate data for
existing SoCs.
