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'.
