Add support to the m68k architecture code for the elf-fdpic loader.
As of commit 1bde925d2354 ("fs/binfmt_elf_fdpic.c: provide NOMMU loader
for regular ELF binaries") it is possible to run normal ELF executables
on nommu systems. These are simple enough to generate and test - even
without actual elf-fdpic toolchain support.
A few minor changes are required to have everything in place, all on the
architecture code side. The largest required addition is minimal regset
support (for elf-fdpic core dumping), otherwise a couple of cleanups and
some definitions is all that is required.
Note that this is only supporting nommu mode on the m68k at this time.
Changes will be required to the mm_context_t type to support elf-fdpic
with MMU enabled on m68k.
