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.
