a81cbd2da4 xtensa: enforce slab alignment to maximum register width 
XCHAL_DATA_WIDTH is the maximum register width, slab caches should be
aligned to this.

Theoretical fix as all variants have had an XCHAL_DATA_WIDTH of 4
(wordsize) for now.  But the S6000 variant will raise this to 16.

367b8112fe xtensa: move headers files to arch/xtensa/include 
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.
