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.
