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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
