This patch adds bindings for Intel KeemBay Display
v2: review changes from Rob Herring v3: review changes from Sam Ravnborg (removed mipi dsi entries, and encoder entry, connect port to dsi) MSSCAM is part of the display submodule and its used to reset LCD and MIPI DSI clocks, so its best to be on this device tree.
