[PATCH] ALSA: hda/hdmi: Add pins with jack detection support

[Kai-Heng Feng]

HDMI on some platforms doesn't enable audio support because its Port
Connectivity [31:30] is set to AC_JACK_PORT_NONE:
Node 0x05 [Pin Complex] wcaps 0x40778d: 8-Channels Digital Amp-Out CP
  Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
  Amp-Out vals:  [0x00 0x00]
  Pincap 0x0b000094: OUT Detect HBR HDMI DP
  Pin Default 0x58560010: [N/A] Digital Out at Int HDMI
    Conn = Digital, Color = Unknown
    DefAssociation = 0x1, Sequence = 0x0
  Pin-ctls: 0x40: OUT
  Unsolicited: tag=00, enabled=0
  Power states:  D0 D3 EPSS
  Power: setting=D0, actual=D0
  Devices: 0
  Connection: 3
     0x02 0x03* 0x04

Those pins were filtered out by commit 116dcde63806 ("ALSA: HDA: Remove
unconnected PCM devices for Intel HDMI"). However, jacks that support
detection won't have the issues the commit addresses.

So still add the pin if it supports jack detection.
