Sandy and Ivy Bridge processors use the same socket, and a mainboard
with the socket can support both types of CPUs. However, they use
different native graphics init code for LVDS and cause a crash if
running the wrong code.
This change detects the CPU type and then selects the right code to
run. It will add some more code in ramstage. It also merges the
{SANDY,IVY}BRIDGE_LVDS symbol to one SANDYBRIDGE_IVYBRIDGE_LVDS.
Tested on a Lenovo T520 with i7-2630qm and i7-3720qm

In the same time remove few native gfx options which were improperly set
and only added dead code to the binary.

If any path in a method returns a value, IASL expects that all paths
within that method will return a value.
Presumably the MKHP method wouldn't get called unless there were a
pending event, but if no event is found, return a zero.
Fixes IASL warning:
dsdt.aml 1785: Method (MHKP, 0, NotSerialized)
Warning 3115 - ^ Not all control paths return a value (MHKP)
This was the only IASL warning in most lenovo mainboards.

We've actually got more warnings now than when I first tested IASL
warnings as errors. Because of this, I'm adding it with the option
to have it disabled, in hopes that things won't get any worse as we
work on fixing the IASL warnings that are currently in the codebase.
- Enable IASL warnings as errors
- Disable warnings as errors in mainboards that currently have warnings.
- Print a really obnoxious message on those platforms when they build.
***** WARNING: IASL warnings as errors is disabled! *****
***** Please fix the ASL for this platform. *****

This is a sad story. We have three different code paths for
sandybridge and ivybridge: proper native path, google MRC path, and,
everyone's favorite: Intel FSP path. For the purpose of this patch,
the FSP path lives in its own little world, and doesn't concern us.
Since MRC was first, when native files and variables were added, they
were suffixed with "_native" to separate them from the existing code.
This can cause confusion, as the suffix might make the native files
seem parasitical.
This has been bothering me for many months. MRC should be the
parasitical path, especially since we fully support native init, and
it works more reliably, on a wider range of hardware. There have been
a few board ports that never made it to coreboot.org because MRC would
hang.
gigabyte/ga-b75m-d3h is a prime example: it did not work with MRC, so
the effort was abandoned at first. Once the native path became
available, the effort was restarted and the board is now supported.
In honor of the hackers and pioneers who made the native code
possible, rename things so that their effort is the first class
citizen.
