Subject: drm/sun4i: Ignore the generic connectors for components

From: Maxime Ripard <[email protected]>

[ Upstream commit 49baeb074783f5bdf770dc9fac5fbb2837190583 ]

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.
