Some Allwinner SoCs have 2 display pipelines, as in 2 of each components, including the frontend, backend, TCON, and any other extras. As the backend and TCON are always paired together and form the CRTC, we need to know which backend or TCON we are currently probing, so we can pair them when initializing the CRTC. This patch figures out the backend's ID from the device tree and stores it in the backend's data structure. It does this by looking at the "reg" property of any remote endpoints connected to the backend's input port.
