I have worked with the AT91SAM9260 on a project which is currently suspended
(other priorities), where we had a simiar problem, with a codec on SPI.
Every time audio was started (capture or playback) the channels could be
swapped. Solving that issue remains TODO when we restart.
There was a thread on alsa-devel last month 'Soc Atmel SSC stereo problem'
with some suggestions.
