Get rid of old hybrid graphics driver and use the new one.
1. Disable IGD and PEG in early romstage.
The PEG port will get disabled on devices that do not have a
discrete GPU. The power savings are around ~1Watt.
The disabled IGD does no longer waste GFX stolen memory.
2. Get rid of PCI driver
The Nvidia GPU can be handled by the generic PCI driver and allows
to use the ACPI _ROM generator for Switchable graphics.
3. Settings are stored in devicetree.
One driver for all Lenovo hybrid graphics capable devices.
4. Add support for Thinker1 GPU power handling.
Only boards that do use reference design 2012 are known to be
supported. Needs test on boards that do you use reference design 2013.
Should reduce idle power consumption when using IGD by ~5Watt.
Tested on Lenovo T430 without DGPU. PEG port is disabled.
Needs test on all devices.

All affected boards did the same USE_NATIVE_RAMINIT distinction or
actually selected USE_NATIVE_RAMINIT. Also update autoport.

In the single GPU configuration, the T420 has an LVDS port, one DP++
and one VGA port connected to the IGD. Docking solutions feature up to
two additional DP/DVI-D ports, also directly connected to the IGD.
This makes the list of ports to probe pretty long (takes about 70ms
if nothing but LVDS is connected). We could save about 20~30ms if we'd
limit the ports in case we are not docked or have a discrete GPU.

This timeout is probably needed on all devices with Lenovo H8 embedded
controllers so set the default there.

This is based on t420s. Tested on a T420 without discrete GPU.
There is no support for nvidia gpu and optimus.
