hw intf blocks are needed only during encoder enable to program
timing engines(for video panels). encoder->enable is triggered
only after atomic_modeset at which point we assign the
resources for the display pipeline. This patch defers the
hw_intf look-up until encoder enable.
changes in v2:
- none
changes in v3:
- none
