Subject: [PATCH v4 0/6] Add pinctrl support for Baytrail

Add support for pin control (pin muxing and pin configuration) for Baytrail
platform.

It follows the design in pinctrl-intel.c, but could not use the
implementation in pinctrl-intel since there were significant differences:
	- gpio pin pads are not ordered
	- per group functions: for setting a certain mode, there are groups
	that need setting pins with different values; for instance, for
	setting USB ULPI pins to GPIO function, pin 2 (GPIO_SUS1) needs
	to be set to function 1, wihle all other from the group need to be
	set to 0
	- communities only need pin base and count as specific data
	- irq set type only clears all flags, while the actual type setting
	is made in the byt_irq_unmask function, which does not comply with
	the intel pinctrl implementation

Changes from v3:
	- fix GPIO_* pin names to match naming conventions used in other
	Intel pinctrl drivers

Changes from v2:
	- remove comment for each enumerated pin
	- apply pin naming conventions used in other Intel drivers

Changes from v1:
	- fix reg, reg_val and byt_soc_data not used variables warnings
