intel_extreme: Sandy/IvyBridge fix 4 lanes DP detect, fully pgm eDP link

intel_extreme: decoupled PIPE/eDP link programming from FDI train, fixed eDP pgm error.

intel_extreme: if no EDID found use boottime EDID if there

intel_extreme: for Ivy/SandyBridge added eDP programming for laptops.

intel_extreme: reduce use of display_mode where display_timing is enough

In most cases we don't need to use the complete display_mode struct and
we just need the timings. This will avoid future confusion between the
virtual width/height and the actual display timings, if we implement
scrolling someday.

intel_extreme: Implement Snb PCH FDI link training

Fix gcc2 build

Use %B_PRIx32 instead of %x

Fixes warnings that were being treated as errors, and thus fixes the build.

intel_extreme: Implement Ilk PCH FDI link training

* IronLake tested and FDI says it trains successfully
* Still no LVDS video on Ilk

intel_extreme: Set FDI PLL RX lane count when enabling

intel_extreme: Tab cleanup; no functional change.

* It seems like the Atom editor has been injecting
spaces in strange spots.
* Clean up spaces. Should help gcc6 as well.
* Sorry for the mess! Atom is on probation.

intel_extreme: Drop out of FDI autotrain after success

intel_extreme: return after proper FDI auto-train

intel_extreme: Enable FDI PLL's before FDI training

intel_extreme: More FDI training work

* IvyBridge or higher can auto-train.
* Linux doesn't use this feature, however
manual FDI link training is *really*
complex... lets try auto-training first.

intel_extreme: Enable / Disable FDI TX/RX

intel_extreme: First work at programming FDI

intel_extreme: Rework card identification defines

* Be more verbose on flag type
* Add additional groups
* Add additional families
* Correctly assign later models

intel_extreme: Rebase and refactor mmlr's work from 2013

* New port storage classes and cleaner logic
