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.
