[PATCH] arm64: perf_event: Remove wrongfully used inline

[Raphael Gault]

The functions armv8pmu_read_counter() and armv8pmu_write_counter()
are `static inline` while they are only referenced when assigned
to a function pointer field in a `struct arm_pmu` instance.

The inline keyword is thus counter intuitive and shouldn't be used.

This looks like a sensible cleanup, so:

Will, I assume you'll pick this up.

Thanks,
Mark.
