drm/amd/display: Test backlight ABM property attach

Browse source

[WHAT]
Cover the eDP success path of amdgpu_dm_setup_backlight_device() where the
ABM level property is attached to the connector. A DRM-managed connector
fixture (drmm_mode_config_init + drmm_connector_init) lets the test verify
that one property is added and that its value is ABM_SYSFS_CONTROL.
