drm/atmel-hlcdc: Fix output initialization

drm_of_find_panel_or_bridge() is expecting np to point to the encoder
node, not the bridge or panel this encoder is feeding.
Moreover, the endpoint parameter passed to drm_of_find_panel_or_bridge()
is always set to zero, which prevents us from probing all outputs.

We also move the atmel_hlcdc_rgb_output allocation after the
panel/bridge detection to avoid useless allocations.
