gma: Do detection and connectors init after `All_Off'

The `Port_Detect.Init' and `Connectors.Init' steps have grown over time.
They used to do one-time initialization that could be done independently
from the current hardware state. However, with the introduction of Tiger
Lake, it becomes more reasonable to ensure a disabled state before those
init steps.

Actually, we already program DDI buffers in `Connectors.Init' that pro-
bably shouldn't change when the hardware is running. It only didn't mat-
ter because everybody is supposed to write the same static values.

Tested on CFL with port detection after power & clocks init.
