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")
Cc: stable@vger.kernel.org # v3.19+
