The result being that for NTSC bottom-top field order, the CSI would swap fields and capture in top-bottom order. Instead, base field swap on the field order of the input to the CSI, and the field order of the requested output. If the input/output fields are sequential but different, swap fields, otherwise do not swap. This requires passing both the input and output mbus frame formats to ipu_csi_init_interface(). Move this code to a new private function ipu_csi_set_bt_interlaced_codes() that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and possibly interlaced BT.1120 in the future). When detecting input video standard from the input frame width/height, make sure to double height if input field type is alternate, since in that case input height only includes lines for one field.

For full and partial planar 4:2:2 (YUV422P, NV16), chroma line stride must be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12), chroma line stride must _not_ be doubled, since a single chroma line is shared by two luma lines.
