__kernel_map_pages() is almost identical for PPC32 and RADIX. Refactor it. On PPC32 it is not needed for KFENCE, but to keep it simple just make it similar to PPC64. Move the prototype of hash__kernel_map_pages() into mmu_decl.h to allow IS_ENABLED() to work on 32-bit.

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.
