W-Box Box Level PMON state

The following registers represent the state governing all box-level PMUs in the W-Box.
The _GLOBAL_CTL register contains the bits used to enable monitoring. It is necessary to set the
.ctr_en/fixed_en bit to 1 before the corresponding data register can collect events.
If an overflow is detected from one of the W-Box PMON registers, the corresponding bit in the
_GLOBAL_STATUS.ov/ov_fixed field will be set. To reset the overflow bits set in the
_GLOBAL_STATUS.ov/ov_fixed field, a user must set the corresponding bits in the
_GLOBAL_OVF_CTL.clr_ov/clr_ov_fixed field before beginning a new sample interval.
