[PATCH] MIPS: perf: remove unused counters_per_cpu_to_total function

[Florian Fainelli <florian@openwrt.org>]

This function is currently unused and causes a build error:
cc1: warnings being treated as errors
arch/mips/kernel/perf_event_mipsxx.c:166: error: 'counters_per_cpu_to_total' 
defined but not used
make[2]: *** [arch/mips/kernel/perf_event_mipsxx.o] Error 1
make[2]: *** Waiting for unfinished jobs....

It was first introduced in commit:
82091564: MIPS: perf: Add support for 64-bit perf counters.
and is applicable to 3.2 onwards.
