Add hwpmc(4) support for the PowerPC 970 class processors, direct events.
This also fixes asserts on removal of the module for the mpc74xx. The PowerPC 970 processors have two different types of events: direct events and indirect events. Thus far only direct events are supported. I included some documentation in the driver on how indirect events work, but support is for the future. MFC after: 1 month
