Change subject: drvs/lenovo/hybrid_graphics: Switch to new hybrid driver
......................................................................
drvs/lenovo/hybrid_graphics: Switch to new hybrid driver
Get rid of old hybrid graphics driver and use the new one.
Disable IGD and PEG in early romstage and remove the PCI based driver.
Add GPIO configuration in devicetree.
Needs test on all devices.
