Rob Herring fb242be88d arm64: perf: Fix 64-bit event counter read truncation
commit 7bb8bc6eb550116c504fb25af8678b9d7ca2abc5 upstream.

Commit 0fdf1bb759 ("arm64: perf: Avoid PMXEV* indirection") changed
armv8pmu_read_evcntr() to return a u32 instead of u64. The result is
silent truncation of the event counter when using 64-bit counters. Given
the offending commit appears to have passed thru several folks, it seems
likely this was a bad rebase after v8.5 PMU 64-bit counters landed.
