Building the Tegra DRM out-of-tree module against the current upstream
mainline kernel is failing and errors such as the following are seen.
ERROR: modpost: module tegra-drm-next uses symbol dma_buf_detach from
namespace DMA_BUF, but does not import it.
ERROR: modpost: module tegra-drm-next uses symbol dma_buf_vunmap from
namespace DMA_BUF, but does not import it.
ERROR: modpost: module tegra-drm-next uses symbol dma_buf_put from
namespace DMA_BUF, but does not import it.
Following upstream commit 16b0314aa746 ("dma-buf: move dma-buf symbols
into the DMA_BUF module namespace"), it is now necessary to import the
DMA_BUF module namespace into the Tegra DRM driver to fix this.

For Linux v5.11, there are a some changes to the DRM APIs that require
updates to the Tegra DRM driver. These are:
1. Commit 6619ccf1bb1d ("dma-buf: Use struct dma_buf_map in
dma_buf_vmap() interfaces") changes to the dma_buf_vmap() and
dma_buf_vunmap() APIs to pass a new parameter of type
'struct dma_buf_map'.
2. Commit 351f950db4ab ("drm/atomic: Pass the full state to CRTC atomic
enable/disable) and commit f6ebe9f9c923 ("drm/atomic: Pass the full
state to CRTC atomic begin and flush") changes the structure type
passed to APIs referenced by the commits.
Finally, commit dd311c6fe8af ("drm/tegra: Introduce GEM object
functions") update the Tegra DRM driver to use GEM object functions.
Update the Tegra DRM driver to support these updated APIs for
Linux v5.11+ and align with the latest changes.

Add the upstream tegra-drm driver with the 'Host1x/Tegra UAPI' series
[0] applied. This driver will be built as an external module for testing
and development with upstream Linux kernels.
The following modifications have been made to the series posted upstream
1. Update the Makefile to always build the driver as a module
2. Always enable the tegra_drm_ioctl_xxx in the tegra_drm_ioctls and
remove the dependency on CONFIG_DRM_TEGRA_STAGING.
3. Rename the include/uapi/drm/tegra_drm.h to
include/uapi/drm/tegra_drm_next.h to avoid conflicts with upstream
headers when building as an external module.
5. Rename the module that is built to be tegra-drm-next.ko instead of
tegra-drm.ko to avoid any depmod conflicts with the upstream driver.
