control:p10bmc: OCC inactive fan floor event

Set and hold a fan floor unless all OCCs are active.

Example of a boot with just this floor event:
zone-floor0: count_state_floor-2 is setting floor hold to 10000",
zone-floor0: Setting new floor to 10000",
zone-floor0: count_state_floor-2 is removing floor hold",
zone-floor0: No set floor exists, using default floor"
