c451280883 PCI: tegra264: dma: Fix mis-matches with ICD
Fix tegra_pcie_dma_stop() return type to bool instead of tegra_pcie_dma_status_t.
Add NULL checks and atleast one DMA channel enable status in
tegra_pcie_dma_initialize().

23e3912ef7 PCI: tegra264: Fix build issues using conftest
The Tegra264 PCIe drivers don't build for kernels that don't have:

1. The structure mrq_pcie_request_req defined
2. The function pci_epc_deinit_notify() present

This is currently being handling by building a dummy driver for kernels
that don't have these. To simplify this, use conftest to detect if the
above are present and modify the Tegra264 PCIe driver accordingly if
they are not present. By using conftest we can remove the Makefile
variable 'NV_OOT_PCIE_T264_SOC_SKIP_BUILD' and ccflag
'DNV_CONFIG_PCIE_TEGRA_DMA_DISABLE'.

Finally, the PCIe drivers are always built as modules so simplify the
Makefile and remove the usage of 'CONFIG_TEGRA_OOT_MODULE'.

4ab2bfd19c PCI: Fix crash in PCIe dma test deinit
PCIe deinit function tegra_pcie_dma_deinit() takes cookie double pointer
as argument. Add null check for pointer stored in double pointer variable
