Let's get rid of the platform if ladders in
intel_digital_port_connected() and make it a vfunc. Now the if
ladders are at the encoder initialization which makes them a bit
less convoluted.
v2: Add forward decl for intel_encoder in intel_tc.h
v3: Duplicate stuff to avoid exposing platform specific
functions across files (Jani)
