ata: pata_pxa: convert not to use dma_request_slave_channel()

Browse Source 
dma_request_slave_channel() is deprecated. dma_request_chan() should
be used directly instead.

Switch to the preferred function and update the error handling accordingly.
While at it, also propagate the error code that is now available.
