drm/tegra: Fix build for Linux v6.4

Browse Source 
In Linux v6.4, the various drm_scdc_get/set functions were updated to
take an argument of type 'struct drm_connector'. Add a new test to the
conftest script that checks if this argument is used and use the
definition created by conftest to select which version of the function
is used.
