drm/i915/cnl: Enable DDI-F on Cannonlake.
Now let's finish the Port-F support by adding the
proper port F detection, irq and power well support.
v2: Rebase
v3: Use BIT_ULL
v4: Cover missed case on ddi init.
v5: Update commit message.
v6: Rebase on top of display headers rework.
v7: Squash power-well handling related to DDI F to this
patch to avoid warns as pointed out by DK.
v8: Introduce DDI_F_LANES to PG2. (DK)
v9: Squash in the PORT_F case for enabling DP MST encoder. (DK)
