Provides basic enablement for perf branch stack sampling framework on POWER8 processor based platforms. Adds new BHRB related elements into cpu_hw_event structure to represent current BHRB config, BHRB filter configuration, manage context and to hold output BHRB buffer during PMU interrupt before passing to the user space. This also enables processing of BHRB data and converts them into generic perf branch stack data format.
