[PATCH AUTOSEL 6.7 11/23] drm/ttm/tests: depend on UML || COMPILE_TEST

From: Christian König <christian.koenig@xxxxxxx>

[ Upstream commit 9d3f8a723c7950e56e0b95ab84b572caee29e065 ]

At least the device test requires that no other driver using TTM is
loaded. So make those unit tests depend on UML || COMPILE_TEST to
prevent people from trying them on bare metal.
