[v1,0/4] drm: tc358764: support drm bridge connector helper

Message

Somehow Laurent tricked me into updating a bridge driver.
In reality, having updated a driver yourself makes for much
better understanding of what is going on.
So in order to provide proper review feedback I deciced to give
it a spin. tc358764 was selected as it is a simple bridge driver,
so a good driver to start out with.

We are moving to a model where the panel tell what connector
it uses - so this patch assumes this model is in place.

The only device tree in the kernel that uses tc358764
use the boe,hv070wsa-100 panel, so update this panel to report
the correct connector type to support the model described above.

The "drop drm_connector_(un)register" patch drops some
unnessesary calls related to drm_connector.

Next update tc358764 to use drm_panel_bridge - which was a
nice simplification of the driver.

The last patch to support optional connector creation was
then simple to implement.

The patchset has not seen any run-time test.
So testing feedback is appreciated. The only in-kernel
user seems to be: exynos5250-arndale

Review feedback is likewise appreciated/expected - bridge
drivers is not my expertise area.
