drm/tegra: Changes for v5.13-rc1

Browse source 
The changes this time around contain a couple of fixes for host1x along
 with some improvements for Tegra DRM. Most notably the Tegra DRM driver
 now supports the hardware cursor on Tegra186 and later, more correctly
 reflects the capabilities of the display pipelines on various Tegra SoC
 generations and knows how to deal with the dGPU sector layout by using
 framebuffer modifiers.
