Ilkka Koskinen 403edfa436 arm64/arm: arm_pmuv3: perf: Don't truncate 64-bit registers 
The driver used to truncate several 64-bit registers such as PMCEID[n]
registers used to describe whether architectural and microarchitectural
events in range 0x4000-0x401f exist. Due to discarding the bits, the
driver made the events invisible, even if they existed.

Moreover, PMCCFILTR and PMCR registers have additional bits in the upper
32 bits. This patch makes them available although they aren't currently
used. Finally, functions handling PMXEVCNTR and PMXEVTYPER registers are
removed as they not being used at all.

Fixes: df29ddf4f0 ("arm64: perf: Abstract system register accesses away")
