When the "panel power saving" property is set to forbidden the
compositor has indicated that userspace prefers to have color
accuracy and fidelity instead of power saving.
Verify that the sysfs file behaves as expected in this situation.

Is there a purpose of setting target abm to 0 (disabled) here?
I suppose it should fail given that we've set REQUIRE_COLOR_ACCURACY. Though I'm
not sure why we can't keep target = 3.
