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'.

The following functions are exported from nvmap code and being used by
nvgpu in non-DriveOS code like L4T. Hence we should not include these
functions in embedded builds.
- nvmap_get_vpr_dev
- nvmap_get_vpr1_dev
The following functions get used in DriveOS as well by nvmap, but no
need to export to nvgpu, as they are not supposed to be used on DrivOS
by other modules. Hence do not export this in embedded builds.
- nvmap_dma_alloc_attrs
- nvmap_dma_free_attrs
In order to achieve this, define a new config file for embedded-linux
and define config and ccflag which can be used in any OOT driver to
differentiate between embedded-linux and non embedded-linux builds.

stable.

For some of the kernel tegra_bpmp is part of core kernel and
hence it is nto required to use the OOT tegra_bpmp driver.
However, some packaging still expect the tegra_bpmp.ko from
the OOT path. To trick the packaging file, add dummy tegra_bpmp
driver which does not have anything other than module_init/module_exit.
