[PARISC] Update harmony from parisc tree
o Added a control for the input source (which can be either
"line" or "mic")
o Mute the speaker/line-out/headphone outputs by default.
o Increased the buffer size from 10 pages to 16.

ALSA Harmony was resetting the capture position when
preparing the capture substream, which it shouldn't do.
This should fix the problem.

ALSA Harmony should no longer play junk (left in the buffers
from a previous stream) at the start of a new stream.
Implement the monitor mixer channel for ALSA Harmony.
Also prevent snd_harmony_volume_get from returning negative values.

Use the graveyard/silence buffers in ALSA Harmony.
