bus: mhi: host: Allow configuration of bidrectional channels

Browse Source 
Certain offload channels such as ones for satellite driver
usecases are required to be configured as bidrectional channels.
Allow it to ensure devices are created for them and the channels
are probed.

Added __attribute__((__fallthrough__)) statements to suppress
compiler error.
