The xhci platform driver needs to work on systems that either only
support 64-bit DMA or only support 32-bit DMA. Attempt to set a
coherent dma mask for 64-bit DMA, and attempt again with 32-bit
DMA if that fails.

compile as a module

Applied Micro's X-Gene platform uses ARM64 processors and a
standard, XHCI compatible piece of silicon for USB connectivity.
It only supports 64 bit DMA. Modify the xhci platform driver to
use either 32 bit or 64 bit DMA, as appropriate, and then
modify the platform driver to recognize the ACPI sig
