drm/dp/mst: split connector registration into two parts (v2)
In order to cache the EDID properly for tiled displays, we
need to retrieve it before we register the connector with
userspace, otherwise userspace can call get resources
and try and get the edid before we've even cached it.
This fixes some problems when hotplugging mst monitors,
with X/mutter running. As mutter seems to get 0 modes
for one of the monitors in the tile.
v2: fix warning in radeon
handle tile setting in cached path rather than
get edid path.
