Add Power10 feature function to DT CPU features, along with a Power10 specific init() to initialize PMU SPRs, sets the oprofile_cpu_type and cpu_features. This will enable performance monitoring unit (PMU) for Power10 in CPU features with "performance-monitor-power10". For Power ISA v3.1, BHRB disable is controlled via Monitor Mode Control Register A (MMCRA) bit, namely "BHRB Recording Disable (BHRBRD)". This patch initializes MMCRA BHRBRD to disable BHRB feature at boot for Power10.
