net: smc911x: remove the dmaengine compat need
As the pxa architecture switched towards the dmaengine slave map, the old compatibility mechanism to acquire the dma requestor line number and priority are not needed anymore. This patch simplifies the dma resource acquisition, using the more generic function dma_request_slave_channel(). Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: David S. Miller <davem@davemloft.net>
