media: dt-bindings: media: st,stm32-dcmi: add support of BT656 bus
Add support of BT656 embedded synchronization bus mode in DCMI driver.
Add "bus-type" property and make it required so that there is no
ambiguity between parallel mode (bus-type=5) and BT656 mode (bus-type=6).
BT656 mode allows to save hardware synchro lines hsync & vsync by replacing
them with synchro codes embedded in data stream, hence hsync-active &
vsync-active properties are useless in this mode.
With DCMI, BT656 bus mode is only compatible with 8 bits width data bus.
