gpu: ipu-csi: Check for field type alternate
When the CSI is receiving from a bt.656 bus, include a check for field type 'alternate' when determining whether to set CSI clock mode to CCIR656_INTERLACED or CCIR656_PROGRESSIVE. Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
