Ease the deployment of clkdev by providing a default asm/clkdev.h for
use if the arch does not have an include/asm/clkdev.h.

Due to limitations in Kbuild we manually add clkdev.h to all
architectures that don't have one rather than having the header appear
by default.

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.

Also, use the generic definition mod_arch_specific where possible.

To this end, I've defined three new config bools:

 (*) HAVE_MOD_ARCH_SPECIFIC

     Arches define this if they don't want to use the empty generic
     mod_arch_specific struct.

 (*) MODULES_USE_ELF_RELA

     Arches define this if their modules can contain RELA records.  This causes
     the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
     defined by the arch rather than have the core emit an error message.

 (*) MODULES_USE_ELF_REL

     Arches define this if their modules can contain REL records.  This causes
     the Elf_Rel mapping to be emitted and allows apply_relocate() to be
     defined by the arch rather than have the core emit an error message.

Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

With this, some arch asm/module.h files can be deleted entirely and replaced
with a generic-y marker in the arch Kbuild file.

Additionally, I have removed the bits from m32r and score that handle the
unsupported type of relocation record as that's now handled centrally.

These old drivers are not used anymore, we use the ones in drivers/rtc.

Add swab.h to kbuild.asm and remove the individual entries from
each arch, mark as unifdef as some arches have some kernel-only
bits inside.

Change all users of header files to correct path.
Remove some unneeded headers for arch-v32.

I won't say 'fix', because they still look broken, although this will at
least allow 'make ARCH=CRIS headers_install' to _complete_.

For headers which are exported, we should probably choose between
asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't
rely on a generated symlink. And we certainly can't export an arch/
directory which doesn't even exist.

And the only thing that we seem to include from the arch/ directory is
<asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in
either arch-v10 or arch-v32 _anyway_.

Hinko Kocevar noted that the CRIS architecture subdirs were no longer
exported correctly when doing install_headers.

Correct this by exporting all directories as header-y.

This fixes most of the issues with exported headers on CRIS, although
we do still need to deal with the asm/arch symlink.

These include nothing more than the basic set of files listed in
asm-generic/Kbuild.asm. Any extra arch-specific files will need to be
added.
