Subject[PATCH v6 20/27] Move EM_XTENSA to uapi/linux/elf-em.h
This should never have been defined in the arch tree to begin with,
and now uapi/linux/audit.h header is going to use EM_XTENSA
in order to define AUDIT_ARCH_XTENSA which is needed to implement
syscall_get_arch() which in turn is required to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

Notes:
v6: there is an earlier revision of this patch in xtensa tree where
EM_XTENSA is added to uapi/linux/elf-em.h but arch/xtensa/include/asm/elf.h
remains unchanged
v5: move EM_XTENSA to elf-em.h instead of adding,
I didn't realize it was already defined in the arch tree
v2: added Reviewed-by
