Patch series uses dma engine APIs in pci-epf-test to transfer data using
DMA. It also adds an option "-d" in pcitest for the user to indicate
whether DMA has to be used for data transfer. This also prints
throughput information for data transfer.
Changes from v1:
*) Fixed some of the function names from pci_epf_* to pci_epf_test_*
since the DMA support is now been moved to pci-epf-test.c
