c150e5bd00 Misc: pci-dma-test: Remove dead code 
tegra-pcie-dma-test is initially written with DMA programming part of
it. Now DMA driver is available separate and DMA programming part of
this driver conflicts with actual programming and results in unexpected
behaviour. Remove non DMA driver test interaction code.
