Subject: [PATCH v3 0/2] DCMI BT656 parallel bus mode support

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.
This mode is enabled when hsync-active & vsync-active
fields are not specified in devicetree.
