I'd be happy if bit 2 in device id actually meant "port F", but I'm not
so happy with coming up with rules like this for coincidental things.
More generally, I'm not all that happy about *any* of the INTEL_DEVID
uses in i915_drv.h because it spreads out the device id information, so
I'd rather not add more. I'd rather move towards single point of truth
for device ids.
Okay, so this is late in the review cycles, and part of a more general
problem, so we should probably just go with this for now and come back
to this later.
BR,
Jani.
