Subject: [PATCH v2 drm-dp 08/10] drm/hisilicon/hibmc: fix no showing when no connectors connected

From: Baihan Li <libaihan@...wei.com>

Our chip support KVM over IP feature, so hibmc driver need to support
displaying without any connectors plugged in. Deleting the detect_ctx()
of VGA to make it connected when no connector is detected.

Fixes: 4c962bc929f1 ("drm/hisilicon/hibmc: Add vga connector detect functions")
