media: ti-vpe: cal: Move all sensor-related init to .bound() notifier

Browse Source 
The initialization of the context based on the connected sensor is split
between the async notifier .bound() and .complete() operations. Move it
all to a separate function and call it from .bound() operation to
prepare for the move of the notifiers from the contexts to the cal_dev.
Only V4L2 registration is kept in the .complete() operation.
