This sturct is memcpy'd to the mdp5_encoder struct, and then later to the mdp5_ctl struct. Instead of copying around interface data, create mdp5_interface instances in mdp5_init, like how it's done currently done for pipes and layer mixers. Pass around the interface pointers to mdp5_encoder and mdp5_ctl. This simplifies the code, and allows us to decouple encoders from INTFs in the future if needed.
