Pin control changes for the v3.11 kernel cycle:

- A large slew of improvements of the Genric pin configuration
   support, and deployment in four different platforms:
   Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD,
   get device tree parsing and debugfs support into shape.
 
 - We also have device tree support with generic naming conventions
   for the generic pin configuration.
 
 - Delete the unused and confusing direct pinconf API. Now state
   transitions is *the* way to control pins and multiplexing.
 
 - New drivers for Rockchip, TZ1090, and TZ1090 PDC.
 
 - Two pin control states related to power management are now
   handled in the device core: "sleep" and "idle", removing a lot
   of boilerplate code in drivers. We do not yet know if this is
   the final word for pin PM, but it already make things a lot
   easier to handle.
 
 - Handle sparse GPIO ranges passing a list of disparate pins, and
   utilize these in the new BayTrail (x86 Atom SoC) driver.
 
 - Make the sunxi (AllWinner) driver handle external interrupts.
 
 - Make it possible for pinctrl-single to handle the case where
   several pins are managed by a single register, and augment it to
   handle sleep modes.
 
 - Cleanups and improvements for the abx500 drivers.
 
 - Move Sirf pin control drivers to their own directory, support
   save/restore of context and add support for the SiRFatlas6 SoC.
 
 - PMU muxing for the Dove pinctrl driver.
 
 - Finalization and support for VF610 in the i.MX6 pinctrl driver.
 
 - Smoothen out various Exynos rough edges.
 
 - Generic cleanups of various kinds.
