arm64: perf: Add support for Armv8.1 PMCEID register format
Armv8.1 allocated the upper 32-bits of the PMCEID registers to describe
the common architectural and microarchitecture events beginning at 0x4000.
Add support for these registers to our probing code, so that we can
advertise the SPE events when they are supported by the CPU.
