perf/marvell_cn10k: Fix TAD PMU register offset

The existing offset of TAD_PRF and TAD_PFC registers are incorrect.
Hence, fix with the right register offsets.

Also, drop read of TAD_PRF register in tad_pmu_event_counter_start()
since we don't have to preserve any bit fields and always write
an updated value.
