drm/amdgpu: Partially revert "drm/amdgpu: update drm_display_info correctly when...

[ Upstream commit 602ad43c3cd8f15cbb25ce9bb494129edb2024ed ]

This partially reverts 20543be93ca45968f344261c1a997177e51bd7e1.

Calling drm_connector_update_edid_property() in
amdgpu_connector_free_edid() causes a noticeable pause in
the system every 10 seconds on polled outputs so revert this
part of the change.
