[Intel-gfx] [i915] monitor is not detected unless it was active during boot

I checked both monitors, on displayport they work, on HDMI they share the
same trouble.

An interesting observation is that when plug the monitor into another
system which has an older nvidia card using nouveau (only HDMI is
available, card is too old for displayport).
It seems that the i2c connection is unreliable, sometimes more or less data
is retrieved, but never all of it seems, and sometimes none.

I wonder if there is some sensitivity to i2c speed.

My general observation of these monitors is that they are slow to turn on
on displayport (locking in a mode takes some time), but on hdmi it is
faster, is there some kind of throttling going on the displayport side that
is being ignored on the HDMI side?
