Subject: [PATCH v2 0/3] pinctrl/broxton: enable platform device in the absent of ACPI enumeration

Hi,
The patches are to cater the need for non-ACPI system whereby
a platform device has to be created in order to bind with
Apollo Lake Pinctrl GPIO platform driver.

The MMIO BAR is accessed over the Primary to Sideband bridge
(P2SB). Since the BIOS prevents the P2SB device from being
enumerated by the PCI subsystem, so we need to hide/unhide P2SB
to lookup the P2SB BAR and pass the PCI BAR address to the gpio
platform driver.

All these three patches have dependencies on each other.

Changes from V1:
	- Add new config option CONFIG_X86_INTEL_NON_ACPI and "select PINCTRL"
	  to fix kbuildbot error
