From: Robin Snyders <robin@snyders.xyz>
DISPLAY_PORT_RX is a receive port, so audio flows into it from a front end
and out to the display. Every other receive port in this file is declared
with SND_SOC_DAPM_AIF_IN, while transmit ports use SND_SOC_DAPM_AIF_OUT.
Declaring DISPLAY_PORT_RX as an output reverses the DAPM graph around it
and prevents a playback path from powering the port. Starting a stream
then leaves the AFE port stopped.
Declare it as an input like the other receive ports. Also pass NULL for
the stream name instead of the string "NULL".
