Hi!

In order to faciliate Will's READ_ONCE() patches:

  https://lkml.kernel.org/r/20200123153341.19947-1-will@kernel.org

we need to fix m68k/motorola to not have a giant pmd_t. These patches do so and
are tested using ARAnyM/68040.

Michael tested the previous version on his Atari Falcon/68030.

Build tested for sun3/coldfire.

Please consider!

Changes since -v1:
 - fixed sun3/coldfire build issues
 - unified motorola mmu page setup
 - added enum to table allocator
 - moved pointer table allocator to motorola.c
 - converted coldfire pgtable_t
 - fixed coldfire pgd_alloc
 - fixed coldfire nocache
