platform/x86: dell_rbu: stop abusing the DMA API
For some odd reason dell_rbu actually seems to want the physical and
not a bus address for the allocated buffer. Lets assume that actually
is correct given that it is BIOS-related and that is a good source
of insanity. In that case we should not use dma_alloc_coherent with
a NULL device to allocate memory, but use GFP_DMA32 to stay under
the 32-bit BIOS limit.
