Juan Pablo Conde 14c27f8293 build(amu): restrict counters (RAZ)
The use of AMU counters at the highest implemented exception level
can expose information about them to lower exception levels, such as
specific behavior happening in the CPU (e.g.: MPMM gear shifting in
TC2). In order to prevent this, read accesses to AMU counters are
restricted by default, so they are RAZ (read-as-zero) from lower
exception levels from now on.
