As we want to enable 32bit support, we need to distanciate the
PMUv3 driver from the AArch64 system register names.
This patch moves all system register accesses to an architecture
specific include file, allowing the 32bit counterpart to be
slotted in at a later time.

arm64: perf: Move PMUv3 driver to drivers/perf2023-03-27T13:01:18+00:00Marc Zyngiermarc.zyngier@arm.com2023-03-17T19:50:20+00:00urn:sha1:7755cec63adeecea3cbbf4032047812c37cf7cc3
Having the ARM PMUv3 driver sitting in arch/arm64/kernel is getting
in the way of being able to use perf on ARMv8 cores running a 32bit
kernel, such as 32bit KVM guests.
This patch moves it into drivers/perf/arm_pmuv3.c, with an include
file in include/linux/perf/arm_pmuv3.h. The only thing left in
arch/arm64 is some mundane perf stuff.
