dmaengine: pxa_dma: fix cyclic transfers
While testing audio with pxa2xx-ac97, underrun were happening while the
user application was correctly feeding the music. Debug proved that the
cyclic transfer is not cyclic, ie. the last descriptor did not loop on
the first.
Another issue is that the descriptor length was always set to 8192,
because of an trivial operator issue.
This was tested on a pxa27x platform.
Fixes: a57e16cf0333 ("dmaengine: pxa: add pxa dmaengine driver")
