Appended one more fix, updated diffstat included below for verification

avr32: at32ap700x: fix typo in DMA master configuration
Commit 4aa5f366431fe (avr32: at32ap700x: specify DMA src and dst
masters) specified the masters for the ac97c playback device
but incorrectly set them in the capture slave information rather
than playback.
