arm64: perf: Extend event config for ARMv8.1
Perf has supported ARMv8.1 feature with 16-bit evtCount filed [see c210ae8
arm64: perf: Extend event mask for ARMv8.1], event config should be
extended to 16-bit too, otherwise, if use -e event_name whose event_code
is more than 0x3ff, pmu_config_term will return -EINVAL because function
pmu_format_max_value depends on event config.
This patch extends event config to 16-bit.
