c51582e26e PCI: Enable CONFIG_PCIE_TEGRA_DMA flag in header file 
Tegra DMA driver functions are defined in nvidia-t264 repo and these
functions are used in nvidia-oot repo. Prototypes of these functions
are defined in nvidia-oot repo header file tegra-pcie-dma.h. Enable
CONFIG_PCIE_TEGRA_DMA flag to expose the function prototypes to the
drivers in nvidia-oot repo. This functions should be exposed only if
nvidia-t264 drivers are included in kernel compilation.

1cf1d3f858 pcie: private-soc: Add dummy driver for soc specific pcie driver 
The L4T packaging needs the soc specific dummy driver to be
available always. However, it is not available in generic build and
it creates the packaging/configuration fail.

Add soc specific dummy driver for pcie so that the respective binary
should be available always.
