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'.

Skip T264 PCIE drivers for the few kernels like jammy-src, rhivos-1 and
stable.

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.

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.
