SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

sh4: cache: move exported cache manipulation functions into cache.c

No functional change, moving cache manipulation functions into cache.c
allows to collect all of them in a single location and as a pleasant
side effect cache_control() function can be unexported now.

sh: cache: don't modify CCR from P1 area

cache_wback_all() is a local function and it is called from
cache_control() only, which is in turn jumps to P2 area.

The change fixes an issue when cache_wback_all() returns from P2 to
P1, however cache_control() continues to manipulate with CCR
register, according to the User's Manual this is restricted.

sh4: cache: correct dcache flush to invalidate with write-back

In common usecases flush_cache() assumes both cache invalidation and
write-back to memory, thus in flush_dcache_range() implementation
change SH4 cache write-back only instruction 'ocbwb' with cache purge
instruction 'ocbp', according to the User's Manual there should be no
performance penalty for that.

Note that under circumstances only cache invalidation is expected from
flush_cache() call, in these occasional cases the current version of
flush_cache() works, which is a wrapper over invalidate_dcache_range()
at the moment, this will be fixed in the following change.

sh: avoid multiple definition errors with cache funcs

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.
