[PATCH] x86: add pin control support to Intel low power subsystem

[Mathias Nyman <mathias.nyman@linux.intel.com>]

x86 chips with LPSS (low power subsystem) such as Lynxpoint and
Baytrail have SoC like peripheral support and controllable pins.

At the moment, Baytrail needs the pinctrl-baytrail driver to let
peripherals control their gpio resources, but more pincontrol functions
such as pin muxing and grouping are possible to add later.
