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.

Changes in V11:
	- Select CONFIG_P2SB when CONFIG_X86_INTEL_IVI is enabled instead of
	  CONFIG_LPC_ICH is enabled. This is to fix kbuildbot error.

Changes in V10:
	- No change

Changes in V9:
	- No change

Changes in V8:
	- No change

Errm. INTEL_IVI does not enable MMIO BAR access over P2SB, CONFIG_P2SB does.
