FS#8305 - c200: support docking stations with audio

When the c200 is docked (as detected by the charger discrete being active), switch to line out. This was necessary for the Griffen “iTrip Auto for Sansa” adapter to produce output. I would assume this is necessary for other docking stations.

This is *NOT* a perfect patch, but it is a start and is necessary to make docking stations with audio output work.

Limitations:
* I mute the headphone output, so plugging in a non-docking charger will prevent listening via the headphones while charging. Both can be enabled… if the charger is plugged in, it probably isn’t an issue but that is what the Sansa firmware does.

* The charger/headphones detection is done only on power up. This is suboptimal, but usually “correct.” A better technique would be to hook into the charger status announcements, but I don’t have time right now. :-(

Can this be added to the Current build please?

Any chance you could send me a compiled current release with patch incorporated? I don't have a development environment setup?
