Upstream commit be4306ad928f ("drm/tegra: Don't set allow_fb_modifiers
explicitly") removed the setting of drm->mode_config.allow_fb_modifiers
from the Tegra DRM driver because this is now set by the core. However,
because this is still being set in the Tegra DRM out-of-tree module it
generates a WARNING on boot. Fix this by not setting
drm->mode_config.allow_fb_modifiers for Linux kernels v5.14 and greater.
Upstream commit 6cba3fe43341 ("drm/dp: Add backpointer to drm_device in
drm_dp_aux") added a backpointer that if missing generates another
WARNING on boot so fix this by ensuring the backpointer is populated for
Linux v5.14 kernels and greater.

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.
