perf/marvell: Apply TAD pmu errata to cn10k silicons
commit 3752a85a71a4f6ed7ee7b0a786b5e1c66686a3d3 from git@git.assembla.com:cavium/WindRiver.linux.git TAD performance counters continue to increment counting even when the counter is disabled. This workaround implements writing the control register with the ALLOC_ANY event along with an unsupported partition id before disabling the counter.
