The output pad's field type was being passed to ipu_csi_init_interface(),
in order to deal with field type 'alternate' at the sink pad, which
must be translated to either 'seq-tb' or 'seq-bt' to be understood by
ipu_csi_init_interface(). Doing so breaks the CSI interface setup if
the output pad field type is set to 'none' and the input bus type is
BT.656.
So remove that code and pass unmodified sink pad field type to
ipu_csi_init_interface(). The latter function will have to explicity
deal with field type 'alternate' when setting up the CSI interface
for BT.656 busses.
