Adding a Debug version of the UncachedMemoryAllocationLib that will make the PCI DMA address not match the CPU C address for a DMA buffer. The PCI DMA address will generate a page fault if accessed from the CPU. This should make it easy to debug EFI DMA code to make sure it is following the correct rules for which pointer to use.
