sh: clean up asm/string.h

First, remove the !__KERNEL__ block, since U-Boot is always compiled
with -D__KERNEL__.

Second, remove the mention of the non-existing file
arch/sh/lib/strcasecmp.c and the redundant declaration of strcasecmp()
If sh did have a strcasecmp.c file, presumably the header would have
had to #define __HAVE_ARCH_STRCASECMP.

Third, remove the explicit #undefs of various __HAVE_ARCH_* and
redundant declarations of standard functions, which are anyway
declared in linux/string.h. In the linux source tree, those are all
#defines, and indeed linux does have asm implementations of those functions.
