Log Message:
Pull up following revision(s) (requested by macallan in ticket #476):
        sys/dev/sbus/dbrivar.h: revision 1.15
        sys/dev/ic/cs4215reg.h: revision 1.5
        sys/dev/sbus/dbri.c: revision 1.37
overhaul the dbri driver and make it work again in the New Order Of Things
- fix switching between control and data mode
- make sure interrupts can happen in control mode
- implement audioif.commit_settings()
- switch to control mode only if needed - for changes in sample rate or format
  but not for things like volume control
should fix PR 52786
