drivers/dma/fsldma.c:504: error: implicit declaration of function `bus_to_virt'

The following patch solves the conflict types error, but the bus_to_virt
is under the CONFIG_PPC32 ifdef and we had a discuss on the same for the
availability of the function for ppc64 at http://lkml.org/lkml/2007/10/17/524
