dts: bindings: stm32-dcmi: use endpoint based properties

Browse source 
Update the bindings of the stm32-dcmi driver rely on
properties described within the endpoints and already
detailed within the video-interfaces.yaml.

With that, several properties located at the node root
are now moved into the port / endpoint:

  sensor -> endpoint: remote-endpoint-label
  vsync-active -> endpoint: vsync-active
  hsync-active -> endpoint: hsync-active
  pixelclk-active -> endpoint: pclk-sample
  bus-width -> endpoint: bus-width
