Since this will definitely break things,
let's fix it by being a bit more efficient with our MST encoders by
creating one per-CRTC, which allows us to have just the right number of

The main reason I added this was because the radeon driver's hotplugging paths
for DP do a ton of unnessecary probing, and because the driver usually also
checks all connectors every time there's a hotplug (there isn't much of a good
reason for this, it's just an old driver) it's not at all difficu

Since it seems that some vendors are storing the ATIF ACPI methods under
the same handle that ATPX lives under instead of the device's own
