[PATCH v2 08/10] crypto: omap-aes - Convert to dma_request_slave_channel_compat()

From: "Mark A. Greer" <mgreer at animalcreek.com>

Use the dma_request_slave_channel_compat() call instead of
the dma_request_channel() call to request a DMA channel.
This allows the omap-aes driver use different DMA engines.
