Rob Herring (Arm) a4a6e2078d perf: arm_pmuv3: Prepare for more than 32 counters
Various PMUv3 registers which are a mask of counters are 64-bit
registers, but the accessor functions take a u32. This has been fine as
the upper 32-bits have been RES0 as there has been a maximum of 32
counters prior to Armv9.4/8.9. With Armv9.4/8.9, a 33rd counter is
added. Update the accessor functions to use a u64 instead.
