drm/i915: Add primary plane to mask if it's visible
This fixes the warnings like
"plane A assertion failure, should be disabled but not"
that on the initial modeset during boot. This can happen if
the primary plane is enabled by the firmware, but inheriting
it fails because the DMAR is active or for other reasons.
Most likely caused by
commit 36750f284b3a4f19b304fda1bb7d6e9e1275ea8d
