arm64: perf: fix ARMv8 EVTYPE_MASK to include NSH bit

commit 178cd9ce377232518ec17ff2ecab2e80fa60784c upstream.

This is a port of f2fe09b055e2 ("ARM: 7663/1: perf: fix ARMv7 EVTYPE_MASK
to include NSH bit") to arm64, which fixes the broken evtype mask to
include the NSH bit, allowing profiling at EL2.
