media: mt9m114: Update source pad selection and format when sink pad format changes

Browse Source 
Call mt9m114_ifp_update_sel_and_src_fmt() on sink pad format changes to
propagate these downstream.

This is necessary in 2 different scenarios:

1. When passing through RAW10 bypassing the scaler then any sink pad format
changes must be propagated to the crop/compose selections and to the source
pad format.

2. When the scaler is active, then the crop-rectangle cannot be bigger then
the sink pad format minus a 4 pixel border all around. If the sink format
change reduces the size then things also needs to be propagated downstream.

Rather then adding extra code to check for these conditions, simply always
propagate sink pad format changes downstream.
