Add some helpers to extract and apply feature overrides to the bare idreg values. This involves inspecting the value and mask of the specific field that we are interested in, given that an override value/mask pair might be invalid for one field but valid for another. Then, wire up the new helper for the hVHE test - note that we can drop the sysreg test here, as the override will be invalid when trying to enable hVHE on non-VHE capable hardware.

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.
