str[n]cmp functions return negative value if the first string is less
than the second, positive value if the first string is greater than the
second and zero if they are equal. This is important when these
functions are used for sorting/binary search.
With incorrect strcmp return value bsearch was always failing in the
find_symbol_in_section making it impossible to load any module.

Defining memscan() as memchr() is wrong, because the return values of
memscan() and memchr() are different when the character is not found. So
use the generic memscan() implementation to fix this.

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.
Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.
