match_decoder_by_range() and decoder_match_range() both determine if an HPA range matches a decoder. The first does it for root decoders and the second one operates on switch decoders. Tidy these up with clear naming and make the switch helper more like the root decoder helper in style and functionality. Make it take the actual range, rather than an endpoint decoder from which it extracts the range. Require an exact match on switch decoders, because unlike a root decoder that maps an entire region, Linux only supports 1:1 mapping of switch to endpoint decoders. Note that root-decoders are a super-set of switch-decoders and the range they cover is a super-set of a region, hence the use of range_contains() for that case. Aside from aesthetics and maintainability, this is in preparation for reuse.

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.
