drm/bridge: Pass down connector to drm bridge detect hook

Browse Source 
In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.

In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.

Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.
