[PATCH] dma: at_xdmac: use __le32 for dma addresses

The at_xdmac uses a lli structure with a mix of dma_addr_t and __le32
in it. As Russell King pointed out, dma_addr_t could be a non 32-bit
size depending on the kernel configuration. Change all references of
this to __le32 to better match the hardware representation.

Note, this does nothing to fix the discussion of dma vs physical
addresses also brought up during these discussions.

This patch depends on the __le32 descriptor updates posted
previously.
