We could try to add a generic mechanism for describing altmodes in device-properties, but various altmodes will likely need altmode specific configuration. E.g. the display-port altmode needs some way to describe which set of DP pins on the GPU is connected to the USB Type-C connector. As such it is better to have a separate set of altmode specific properties per altmode and this commit adds a property for basic display-port altmode support.
