Hi,

This version contains changes proposed by Matheus in the
v5 review.

Changes from v5:
- patch 2:
  * added an extra argument to pmu_update_cycles() and pmc_is_active()
to consider the case where we want to consider the frozen counter bits
of a previous MMCR0 state
  * added additional logic to allow for FC14/FC56 bits to freeze their
individual counters without stopping the PMU 
- patch 3:
  * changed macro name to PMC_COUNTER_NEGATIVE_VAL and made it unsigned
  * fixed typo in comment
  * removed the extra space after '='
- patch 9:
  * check for FSCR[EBB] before firing the EBB exception
