ALSA: hda - Add support for HDMI HBR passthrough

Passing IEC 61937 encapsulated compressed audio at bitrates over 6.144
Mbps (i.e. more than a single 2-channel 16-bit 192kHz IEC 60958 link)
over HDMI requires the use of HBR Audio Stream Packets instead of Audio
Sample Packets.

Enable HBR mode when the stream has 8 channels and the Non-PCM bit is
set.

If the audio converter is not connected to any HBR-capable pins, return
-EINVAL in prepare().
