From: William Towle <william.towle@xxxxxxxxxxxxxxx>
Add DT entries for vin0, vin0_pins, and adv7612.
Sets the 'default-input' property for ADV7612, enabling image and video
capture without the need to have userspace specifying routing.

[uli: added interrupt, renamed endpoint, merged default-input]
