Prepare for adding support for RZ/G3E and RZ/V2HP SoCs, which have a CRU-IP that is mostly identical to RZ/G2L but with different register offsets and additional registers. Introduce a flexible register mapping mechanism to handle these variations. Define the `rzg2l_cru_info` structure to store register mappings and pass it as part of the OF match data. Update the read/write functions to check out-of-bound accesses and use indexed register offsets from `rzg2l_cru_info`, ensuring compatibility across different SoC variants.

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.
