[PATCH] dma: use %pa to print dma_addr_t

[Olof Johansson]

This resolves some warnings seen when building with CONFIG_ARM_LPAE=y, since
dma_addr_t might then be 64-bit:

  drivers/dma/imx-sdma.c:1092:3: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Wformat=]
  drivers/dma/imx-sdma.c:1166:3: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Wformat=]
