[PATCH v20 04/11] perf: arm_v7_pmu: Drop obvious comments for enabling/disabling counters and interrupts

["Rob Herring (Arm)" <robh@kernel.org>]

The function calls for enabling/disabling counters and interrupts are
pretty obvious as to what they are doing, and the comments don't add
any additional value.
