6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steffen Dirkwinkel s.dirkwinkel@beckhoff.com
commit 71ba1c9b1c717831920c3d432404ee5a707e04b4 upstream.
drm_kms_helper_poll_init needs to be called after zynqmp_dpsub_kms_init. zynqmp_dpsub_kms_init creates the connector and without it we don't enable hotplug detection.
