As the 1X16 format variants are meant to be used with serial busses they have to be treated as 'YCbCr-422 8-bit data input' (0x1) when capturing from CSI-2, which is a valid setting for CSI-2. Commit 78b3f9d75a62 ("media: rcar-vin: Add check that input interface and format are valid") disallowed capturing YUV16 when using the CSI-2 interface. Fix this by using YUV8_BT601 for YCbCr422 when CSI-2 is in use.

To guarantee the same image format is applied to all source pads, propagate the format from the sink pad to the sources, disallowing changing format on a source pad. To support both gen3 and gen4, which feature a different number of source pads, introduce an helper function to return the correct number of pads.

The TXB transmitter only support YUV422 while the TXA one supports multiple formats as reported by the chip's manual in section 9.7. but the HDMI and AFE subdevices only provide RGB888 and YUV422, so only list those ones here.

Setting a new format on the subdevice hence does not actually control the CSI-2 output format, but it's only there for the purpose of pipeline validation. However, there is currently no validation that the supplied media bus code is valid and supported by the device. With the introduction of enum_mbus_codes a list of supported format is now available, use it to validate that the supplied format is correct and use the default UYVY8 one if that's not the case.

Initialize the frame interval to the special case 0/0 that in the max9286 driver represents automatic handling of frame sync. As the frame sync mode is set at s_stream() time, we can remove it from max9286_setup().
