[RFC PATCH V2 08/10] arm64: rename enum debug_el to enum debug_elx to fix "wrong kind of tag"

[panand@redhat.com (Pratyush Anand)]

asm/debug-monitors.h contains definition for debug opcode. So, it will
be needed by asm/uprobes.h.

With enum debug_el it generates following compilation error, since
asm/uprobes.h is included.

lib/list_sort.c:160:8: error: ?debug_el? defined as wrong kind of tag
 struct debug_el {

Therefore rename enum debug_el to enum debug_elx.
