[DRM][AMD][NAVI2] Suspended monitor is being constantly re-detected

Brief summary of the problem:

When my second monitor is suspended, there are constant DRM/UDEV events about it being just plugged on it seems. This creates problems for some DE that listen to UDEV to know when a new monitor is plugged in. It clogs the logs, prompts screen configuration reloading and creates instability of the overall DE, especially in Wayland environment.
