ALSA: intelhdmi - accept DisplayPort pin
HDA036 spec states:
DP (Display Port) indicates whether the Pin Complex Widget supports
connection to a Display Port sink. Supported if set to 1. Note that
it is possible for the pin widget to support more than one digital
display connection type, e.g. HDMI and DP bit are both set to 1.
Also export the DP pin cap in procfs.
