- 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. Approved by: adrian (mentor, implicit) Differential Revision: https://reviews.freebsd.org/D8009
