[PATCH v2 12/21] drm/bridge: parade-ps8622: make connector creation optional

[Sam Ravnborg]

Make the connector creation optional to enable usage of the
parade-ps8622 bridge with the DRM bridge connector helper.

This change moves drm_helper_hpd_irq_event() call in the attach
function up before the connector creation.
