[PATCH 2/8] net: irda/sa1100_ir: convert to dma_request_slave_channel()

[Russell King]

Convert the sa11x0 irda driver to use the more modern
dma_request_slave_channel() method to get the DMA channel, rather than
using dma_request_channel() with a filter function exported by DMA
driver.  This allows us to get rid of the sa11x0-dma.h include.
