drm/tegra: Fix build for Linux v6.17

Browse Source 
The arguments to the function drm_helper_mode_fill_fb_struct() and
function pointer fb_create() have been updated in the Linux v6.17. Add
the necessary conftest tests to check for the new variants of these
functions and update the Tegra DRM driver accordingly.
