arm: Add both .lds files to CLEAN_FILES unconditionally
'clean' target is listed on 'no-dot-config-targets' list in main
Makefile so that conditional statement would yeild the same result
every time. Given how CLEAN_FILES are rm'ed with -f there should be no
harm in specifying them both unconditionally.
