Handle Zaphod mode correctly in radeon_mode_hotplug
We need to scan both screens of the entity for existing connectors, and enumerate DVI & HDMI connectors consistently regardless of which screen they're assigned to. Fixes crash when hot-(un)plugging connectors in Zaphod mode. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93415 Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
