Add support of BT656 embedded synchronization bus.
This mode allows to save hardware synchro lines hsync & vsync
by replacing them with synchro codes embedded in data stream.
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).

version 4:
- Fix typo in commit message
version 3:
- Fix bus_width print to %u as per Sakari comment
version 2:
- As per Sakari remark, revisit commit message and document
BT656 parallel bus mode in bindings
version 1:
- Initial submission
