drm/tests: helpers: Add atomic helpers

[ Upstream commit 66671944e17644804cb0886489e1b8fde924e9b9 ]

The mock device we were creating was missing any of the driver-wide
helpers. That was fine before since we weren't testing the atomic state
path, but we're going to start, so let's use the default
implementations.
