[PATCH 2/2] standardize the dma direction data type

This patch makes the DMA mapping call's dma direction uniform across
all archs as an "int".  This is in response to the rejection of Muli's
patch to make them uniform as "enum dma_data_direction"
(http://lkml.org/lkml/2006/1/24/262).

Thanks,
Jon
