Implement support for the Activity Monitor Unit on Cortex A75 The Cortex A75 has 5 AMU counters. The first three counters are fixed and the remaining two are programmable. A new build option is introduced, `ENABLE_AMU`. When set, the fixed counters will be enabled for use by lower ELs. The programmable counters are currently disabled.
