asm-generic: use asm-generic/unaligned.h for most architectures
There are several architectures that just duplicate the contents
of asm-generic/unaligned.h, so change those over to use the
file directly, to make future modifications easier.
The exceptions are:
- arm32 sets HAVE_EFFICIENT_UNALIGNED_ACCESS, but wants the
unaligned-struct version
- ppc64le disables HAVE_EFFICIENT_UNALIGNED_ACCESS but includes
the access-ok version
- most m68k also uses the access-ok version without setting
HAVE_EFFICIENT_UNALIGNED_ACCESS.
- sh4a has a custom inline asm version
- openrisc is the only one using the memmove version that
generally leads to worse code.
