[ALSA] ymfpci: fix swapped channels in SPDIF output
Modules: YMFPCI driver
The routing of the effect 2/3 channels to the digital output is the
opposite of the rear analog output (left/right swapped).
We make the order correct for the digital output (which will make the
analog rear have the channels swapped) to make AC3 output work.
