This is an alternative to
("drm/i915/dg2: 5th Display output").

We tried to enable the 5th port in order to get rid of
the unclaimed register access, but even after the basic plumbing, we
are still getting and error that the phy failed to calibrate.

So, rather than enabling it and needing another fix on top later, let's
just fix the immediate issue: we are initializing only 4 ports/phys, but
intel_phy_is_snps() returns we have 5, so we access registers we

I'm still bringing "drm/i915/dg2: Drop 38.4 MHz MPLLB tables", as that
is just eliminating dead code.
