It works in Linux Kernel since ARCH is always given from the

Recent builds for SH4 boards fail with a lot of errors like:
cmd_mem.o: In function 'dcache_invalid_range':
include/asm/cache.h:25: multiple definition of 'dcache_invalid_range'
include/asm/cache.h:25: first defined here
This is due to the funcs being defined in the header, but not static
or inline or extern. So move them to the sh4-specific cache.c file.

The ashrsi3 function is used by some commands that aren't in SH2A
default configs (e.g. JFFS2).
The ashrsi3.S file has been copied from Linux.

Not all SuperH toolchains support -mno-fdpic. Chances are good that if
the flag doesn't work, it isn't defaulting to the FDPIC ABI, so the flag
isn't needed. So only add it if it is actually supported.

This renames BOARD_LATE_INIT to CONFIG_BOARD_LATE_INIT.
Along the way it removes some leftover
#define BOARD_LATE_INIT 1
and adds some basic documentation for board specific
callbacks in README.

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.
MAKEALL didn't report any errors related to this that I could see.

This pushes the ugly duplicated arch ifdef lists we maintain in various
image related files out to the arch headers themselves.
