AMU: Add plat interface to select which group 1 counters to enable
A new platform macro `PLAT_AMU_GROUP1_COUNTERS_MASK` controls which group 1 counters should be enabled. The maximum number of group 1 counters supported by AMUv1 is 16 so the mask can be at most 0xffff. If the platform does not define this mask, no group 1 counters are enabled. A related platform macro `PLAT_AMU_GROUP1_NR_COUNTERS` is used by generic code to allocate an array to save and restore the counters on CPU suspend.
