Trivial clean-up for building Tegra DRM by ...
1. Removing the Kconfig file because this is not needed for building
as an external module and we only plan to build this as an external
module.
2. Move the header file 'tegra_drm_next.h' under the Tegra DRM source
directory so that we don't need to pass the path for finding the
header when building Tegra DRM as an external module.
3. Remove the 'CONFIG_DRM_TEGRA_NEXT' variable because we always build
Tegra DRM as a module.

The Host1x driver will skip DMA API calls if the pin call for a
buffer returns a physical address directly. This is not desirable
even when the IOMMU is disabled, because then we don't get the
cache flushing done by DMA API. As such, remove the direct path.
This patch will be included as part of upstream v6 patch.

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.
