kernel: remove already upstream applied patch

Remove 131-MIPS-export-get_c0_perfcount_int.patch which was already applied
in 4.1.6. This fixes the following build error:

arch/mips/ath79/setup.c:217:77: error: redefinition of '__kstrtab_get_c0_perfcount_int'
arch/mips/ath79/setup.c:211:77: note: previous definition of '__kstrtab_get_c0_perfcount_int' was here
arch/mips/ath79/setup.c:217:350: error: redefinition of '__ksymtab_get_c0_perfcount_int'

-Subject: [PATCH] MIPS: export get_c0_perfcount_int()
-
-get_c0_perfcount_int is tested from oprofile code. If oprofile is
-compiled as module, get_c0_perfcount_int needs to be exported, otherwise
-it cannot be resolved.
-
-Fixes: a669efc4a3b4 ("MIPS: Add hook to get C0 performance counter interrupt")
