Move the check that verifies that reservation of fixed area does not cross HIGHMEM boundary and the actual memblock_resrve() call into a helper function. This makes code more readable and decouples logic related to CONFIG_HIGHMEM from the core functionality of __cma_declare_contiguous_nid().

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.
