drm/i915/cnl: Add HPD support for Port F.

Browse Source 
On CNP boards that are using DDI F,
bit 25 (SDE_PORTE_HOTPLUG_SPT) is representing
the Digital Port F hotplug line when the Digital
Port F hotplug detect input is enabled.

v2: Reuse all existent structure instead of adding a
new HPD_PORT_F pointing to pin of port E.
v3: Use IS_CNL_WITH_PORT_F so we can start upstreaming
    this right now. If that SKU ever get a proper name
    we come back and update it.
v4: Rebase on top of digital connected port using encoder
    instead of port.
v5: Moved IS_CNL_WITH_PORT_F definition to the PCI IDs patch.
