media: dt-bindings: mipi-ccs: Add bus-type for C-PHY support
The bus-type property is required for C-PHY support. Add it, including values for CCP2 and CSI-2 D-PHY. Also require the bus-type property. Effectively all new sensors are MIPI D-PHY or C-PHY that cannot be told apart without the bus-type property.
