drm/i915/cnl: Add AUX-F support
On some Cannonlake SKUs we have a dedicated Aux for port F,
that is only the full split between port A and port E.
There is still no Aux E for Port E, as in previous platforms,
because port_E still means shared lanes with port A.
v2: Rebase.
v3: Add couple missed PORT_F cases on intel_dp.
v4: Rebase and fix commit message.
v5: Squash Imre's "drm/i915: Add missing AUX_F power well string"
v6: Rebase on top of display headers rework.
v7: s/IS_CANNONLAKE/IS_CNL_WITH_PORT_F (DK)
v8: Fix Aux bits for Port F (DK)
v9: Fix VBT definition of Port F (DK).
v10: Squash power well addition to this patch to avoid
warns as pointed by DK.
v11: Clean up squashed commit message. (David)
v12: Remove unnecessary handling for older platforms (DK)
Adding AUX_F to PG2 following other existent ones. (DK)
