[PATCH 1/6] drm/i915/mtl: Initial DDI port setup

[Mika Kahola]

From: Clint Taylor <clinton.a.taylor at intel.com>

Initialization sequences and C10 phy are in place to be able to enable
the first 2 ports of MTL. The other ports use C20 phy that still need
to be properly added. Enable the first ports for now, keeping a TODO
comment about the others.
