[PATCH 04/16] powerpc/xmon: use new match_string() helper/macro

[Alexandru Ardelean <alexandru.ardelean@analog.com>]

The change is purely cosmetic at this point in time, but it does highlight
the change done in lib/string.c for match_string().

Particularly for this change, if a regname is removed (replaced with NULL)
in the list, the match_string() helper will continue until the end of the
array and ignore the NULL.
This would technically allow for "reserved" regs, though here it's not the
case.
