Introduces pmc_writeb() function pointer, in the struct rzg2l_pinctrl_data to facilitate writing to the PMC register. On the RZ/V2H(P) SoC, unlocking the PWPR.REGWE_A bit before writing to PMC registers is required, whereas this is not the case for the existing RZ/G2L family. This addition enables the reuse of existing code for RZ/V2H(P). Additionally, populate this function pointer with appropriate data for existing SoCs. Note that this functionality is only handled in rzg2l_gpio_request(), as PMC unlock/lock during PFC setup will be taken care of in the pwpr_pfc_lock_unlock() function pointer.

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.
