Subject: [PATCH 0/2] drivers: perf: arm_pmu: Drop 'pmu_lock' element from 'struct pmu_hw_events'

This series drops 'pmu_lock' usage from all arm platforms which had already
been dropped from arm64 platforms earlier via the following commit.

commit 2a0e2a02e4b7 ("arm64: perf: Remove PMU locking"). 

Afterwards, drop unused 'pmu_lock' element from 'struct pmu_hw_events'. The
series applies on 6.7-rc1 and has been tested on arm64. Although just build
tested for arm platform.
