Add support for the 64-bit endpoint_req register introduced in CSF v4.0+ GPUs. Unlike a simple register widening, the 64-bit variant occupies the next 64 bits after the original 32-bit field, requiring version-dependent access. This change introduces helper functions to read, write, and update the endpoint_req register, ensuring correct handling on both pre-v4.0 and v4.0+ firmwares.

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.
