intel_extreme: probe DP AUX or/and DDC on DDI ports

* the VBT tells whether DDI ports can have both DP and HDMI/DVI as outputs.
* tested on Dell Optiplex 9020 Gen7/Haswell with an HDMI/DP adapter on a DP connector.
* avoids enabling a down DDI port when an EDID is found: the display isn't setup by the BIOS.

intel_extreme: the eDP port on DDI is mostly found on port A

* for eDP a displayport output should also be found als VBT device type.
* should help with #17730

intel_extreme: parse VBT device configs, use this to skip unused ports

* BDB version from 111
* for DDI from Gen9
* for HDMI and DisplayPort from Gen6
* use the first port to create the mode list
* also probe DDI Port A
* the aux channel helps to select the correct dp aux registers.

intel_extreme: hook dp_aux channel to the i2c common ddc for DigitalDisplayInterface ports

This assumes a Gen9 or Gen11 configuration, and aux channel 0. As a result, the same EDID will
be found for every DDI port. The mapping should be found in the VBT.

Tested on KabyLake and JasperLake

intel_extreme: eDP now works on Sandy/Ivy laptops: ticket #17350 i.e.

intel_extreme: sandy/ivybridge DP links to screens are now programmed to the actual mode if possible

intel_extreme:DP links on sky- upto/incl coffeelake are now done (refclk detection added)

intel_extreme: add laptop panel detection and mode scaling for DDI systems

intel_extreme: skylake PLL works, all outputs fully functional.

intel_extreme: skylake/DDI improvements. no resolution changing possible yet (missing DPLL code yet)

intel_extreme: gen4 displayport now sets modes, dualhead clone works.

intel_extreme:dualhead clone mode with displayport works on Sandy/Ivy Bridge.

intel_extreme: don't pgm pipes, follow BIOS for now. Two screens on now i.e.

intel_extreme: LVDS pipe only *has* to be B when gen < 4

intel_extreme: Extend DDI port probing to A-E

* The Linux code made this a bit hard to figure out via
complex define functions, however there can be up to
5 DDI ports (A-E)

intel_extreme: Improve LVDS panel detection robustness

* If older generation, check for mobile. If mobile GPU
is found, make an assumption that a LVDS panel exists
and attempt to leverage the vbios or VESA EDID.

intel_extreme: Power up DDI

intel_extreme: Add initial work for DDI ports

intel_extreme: Clean up DisplayPort Port class

* DisplayPort != DigitalPort
* i2c needs wrapped in DP AUX transaction code
* Mode-setting comes with DP link training as well
* We need to try and share DP code with radeon_hd

intel_extreme: Move rest of pipe control into pipe class

intel_extreme: Don't store pipes within ports

* Store pipes within accelerant, and tell ports
about them.
* Rebrand DisplayPipe class to Pipe

intel_extreme: First work at programming FDI

intel_extreme: Store current display mode on each port

intel_extreme: Let ports pick a pipe if required

intel_extreme: Add initial TMDS modesetting code

intel_extreme: Set mode and pll via pipe-aware class functions

intel_extreme: Begin using new DisplayPipe class

intel_extreme: Add pipe selection for ports

intel_extreme: Start doing mode-setting at port level

* I really hope we can kill head_mode some day
* Break pll code out from mode code
* The LVDS and Digital are smooshed together and
likely need broken apart.

intel_extreme: Dump more info on ports found. Build fixes.

intel_extreme: Rebase and refactor mmlr's work from 2013

* New port storage classes and cleaner logic
