drivers/apple: Add hybrid graphics driver
A hybrid graphics driver for Apple MacBook Pro.
The driver logic is based on lenovo/hybrid_graphics. It is splitted into romstage and ramstage parts.
The mainboard code calls the driver from romstage to get the GPU state. The driver reads the state from the `hybrid_grapihcs_mode` nvram option, switches dGPU power on or off according to the state and returns the state to the mainboard code. The mainboard code then has to hide the disabled PCI device.
The ramstage part handles the graphics muxes. The muxes code is based on the apple-gmux linux driver, originally written by:
* Canonical Ltd. seth.forshee@canonical.com * Andreas Heider, 2010-2012 andreas@meetr.de * Lukas Wunner, 2015 lukas@wunner.de
Tested on MacBook Pro Retina 15 Mid 2012 (MacBook Pro 10,1).
