[PATCH 2/3] drm/fb: add support for not enabling fbcon on non-std displays

[Dave Airlie <airlied@gmail.com>]

From: Dave Airlie <airlied@redhat.com>

We don't want fbcon to get used on non-standard dislays,
don't pass them as enabled connectors to the fb helper setup.

This prevents my HMD from getting disorted fbcon, and from
affecting other displays console.
