Piet Delaney, Marc Gauthier, Joe Taylor, Christian Zankel (and possibly

This constant is defined in all core headers. Remove the redundant
definition which might error out if other includes lead to inclusion
of <variant/core.h>.

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.
