[PATCH] dmaengine: use phys_addr_t for slave configuration

From: Linus Walleij
Date: Fri Apr 26 2013 - 05:07:12 EST

The documentation already says these are physical addresses, and
we have concluded that any translation into the DMA address space
needs to reside in the dmaengine driver, so change the type of
the passed arguments.
