Currently, reserved register fields must be fully described using dummy enum IDs (zeroes), one for each possible state (2^bits states). Add support for describing reserved fields using negative field width values as shorthands, thus removing the need for dummy values. Apart from the obvious size reduction due to the removal of the dummy values, this will also enable merging adjacent reserved fields into a single field, reducing the number of fields to describe, and thus kernel size. Update the checker accordingly.

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.
