Commit e520c410

    "xtensa: convert to asm-generic/hardirq.h"

converted over to using the asm-generic parts, but it also
added the sentinel

	#define ack_bad_irq ack_bad_irq

which tells asm-generic to _not_ use the common ack_bad_irq.

Since e520c410 deleted the duplicated code from the arch specific
file, we _do_ want the asm-generic one in scope.  So delete
the trigger define above which hides it.  In doing so we'll
realize that we've got to delete the almost-duplicate prototype
as well to avoid "static declaration ... follows non-static".

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.
