Finding out whether a sysreg exists has little to do with that register being accessed, so drop the is_write parameter. Also, the reg pointer is completely unused, and we're better off just passing the attr pointer to the function. This result in a small cleanup of the calling site, with a new helper converting the vGIC view of a sysreg into the canonical one (this is purely cosmetic, as the encoding is the same).

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 Restructured Text 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.
