At the moment xtensa uses slab allocator for PTE table. It doesn't work
with enabled split page table lock: slab uses page->slab_cache and
page->first_page for its pages. These fields share stroage with
page->ptl.

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.
