arm: perf: krait: stop using singleton PMU
Currently the krait_pmu_{enable,disable}_event functions use the global cpu_pmu variable while all the other pmu enable/disable functions derive this from the event argument. This patch brings the Krait functions into line with the rest of the PMU backends by deriving the address of the pmu from the event argument.
