Subject: [PATCH v4 07/11] drm/sun4i: Ignore the generic connectors for components
The generic connectors such as hdmi-connector doesn't have any driver in,
so if they are added to the component list, we will be waiting forever for
a non-existing driver to probe.
Add a list of the connectors we want to ignore when building our component
list.
