drm/imx/dcss: get rid of HPD warning message

Browse Source 
When DCSS + MIPI_DSI is used, and the last bridge in the chain supports
HPD, we can see a "Hot plug detection already enabled" warning stack
trace dump that's thrown when DCSS is initialized.

The problem appeared when HPD was enabled by default in the
bridge_connector initialization, which made the
drm_bridge_connector_enable_hpd() call, in DCSS init path, redundant.
So, let's remove that call.

Fixes: 09077bc311658 ("drm/bridge_connector: enable HPD by default if supported")
