drm: omapdrm: fix compiler errors

Regular randconfig nightly testing has detected problems with omapdrm.

omapdrm fails to build when the kernel is built to support 64-bit DMA
addresses and/or 64-bit physical addresses due to an assumption about
the width of these types.

Use %pad to print DMA addresses, rather than %x or %Zx (which is even
more wrong than %x).  Avoid passing a uint32_t pointer into a function
which expects dma_addr_t pointer.
