spi: spi-fsl-dspi: Re-use one volatile regmap for both device types
max_register overrides anything in the volatile ranges, so we can get
away with sharing the same one for both types. In a later commit we'll
add more devices so this avoids adding even more duplication. Also
replace the max_register magic numbers with their register definitions
so it's clearer what's going on.

No functional changes.

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.
