[PATCH] - fix speaker output for toshiba nb205 netbooks

[Nickolas <ultrageek.lloyd@gmail.com>]

this is a quick fix i wrote up a couple days ago to fix speaker output on the Realtek ALC272 codec present in toshiba nb205 netbooks.  presently, speaker output doesn't work at all on this model, regardless of settings in the mixer.  this is because the current driver thinks the speaker is at nid 0x0c instead of the correct 0x17.  i'm not too familiar with this hardware, so i'm not sure that this patch won't have any negative effects for other hardware.  it also seems like a messy way of fixing the problem.  any comments or suggestions are welcome, as is testing for those who have this board.  diffed against the latest git.

Thanks,
Nick
