Landon J. Fuller 8a03f98a8b bhnd(4): Implement common API for IOST/IOCTL register access and core reset
- Added bhnd(4) bus APIs for per-core ioctl/iost register access.
- Updated reset/suspend bhnd(4) APIs for compatibility with ioctl/iost
  changes.
- Implemented core reset/suspend support for both bcma(4) and siba(4).
- Implemented explicit release of all outstanding PMU requests at the bus
  level when putting a core into reset.
