related cleanups: - Require each driver to initalize a mutex in the scsi_low_softc that is shared with the scsi_low code. This mutex is used for CAM SIMs, timers, and interrupt handlers. - Replace the osdep function switch with direct calls to the relevant CAM functions and direct manipulation of timers via callout(9). - Collapse the CAM-specific scsi_low_osdep_interface substructure directly into scsi_low_softc. - Use bus_*() instead of bus_space_*(). - Return BUS_PROBE_DEFAULT from probe routines instead of 0. - No need to zero softcs. - Pass 0ul and ~0ul instead of 0 and ~0 to bus_alloc_resource(). - Spell "dettach" as "detach". - Remove unused 'dvname' variables. - De-spl().
