pinctrl: renesas: rzg2l: Unify OEN access by making pin-to-bit mapping configurable
Refactor the RZG2L pinctrl driver to support reuse of the common
rzg2l_read_oen() and rzg2l_write_oen() helpers across SoCs with
different output-enable (OEN) bit mappings.
Introduce a new `pin_to_oen_bit` callback in `struct rzg2l_pinctrl_data`
to allow SoCs to provide custom logic for mapping a pin to its OEN bit.
Update the generic OEN read/write paths to use this callback when present.
With this change, SoCs like RZ/G3S can reuse the common OEN handling
code by simply supplying their own `pin_to_oen_bit` implementation.
The previously duplicated `rzg3s_oen_read()` and `rzg3s_oen_write()`
functions are now removed.
This improves maintainability and prepares the driver for supporting
future SoCs with minimal duplication.
