gma: Refactor Hotplug_Detect() interface and usage
Checking for hotplug events should be done before any other work to
reduce load and (spurious) debug output. Therefor, use the simpler
`Port_Type` in the interface of `Hotplug_Detect()` so we don't have to
fill the whole `Port_Cfg` before checking for events.
Also, now that it's possible, factor the disabling of a single output
out of `Update_Outputs()`.
