Pinctrl fixes for the v3.10 series:

- Three fixes to make the boot path for device tree work
   properly on the Nomadik pin controller.
 - Compile warning fix for the vt8500 driver.
 - Fix error path in pinctrl-single.
 - Free mappings in error path of the Lantiq controller.
 - Documentation fixes.
