[PATCH v7 3/6] x86/intel-ivi: Add Intel In-Vehicle Infotainment (IVI) systems used in cars support

[Tan Jui Nee <jui.nee.tan@xxxxxxxxx>]

Add support for non ACPI system, such as system that uses Advanced Boot
Loader (ABL) whereby a platform device has to be created in order to bind
with PINCTRL/GPIO.

At the moment, Intel Apollo Lake SoC requires P2SB driver to hide and
unhide P2SB to lookup P2SB BAR and pass the PCI BAR address to GPIO.
