Add "cval->res = 384" quirk for Logitech Webcam C500

Add "cval->res = 384" quirk for Logitech Webcam C500

[Simon]

Hello,

Since some time I am successfully using this workaround

http://mailman.alsa-project.org/pipermail/alsa-devel/2011-March/037657.html

to solve the problem for the Logitech C500 Webcam (046d:0807).
Would it be possible to add this device to the list included in the 
mixer.c file?

Thanks

Logitech C500 (046d:0807) needs the same workaround like other
Logitech Webcams.
