This patch adds the basic assembly code to read BHRB buffer. BHRB entries are valid only after a PMU interrupt has happened (when MMCR0[PMAO]=1) and BHRB has been freezed. BHRB read should not be attempted when it is still enabled (MMCR0[PMAE]=1) and getting updated, as this can produce non-deterministic results.
