arm: dts: Pre-identify panel in device tree

shim layer identifies the panel attached and updates the respective
node in the device tree. Bootloader uses this updated status bit to
identify the panel connected, therby taking the responsibility to
initialize it. In absence of DSI panel [status bit not updated]
bootloader programs DC0 for HDMI.
L4T does not use SHIM layer. Thus, If DSI panel is not pre-identifed
bootloader will initialize DC0 with HDMI.
