Commit Message

Add gpio hog support for board-specific gpio lines:
- put hogs in u-boot.dtsi so as to keep the regular dts files
  in sync with the kernel. The hogs will not be put in the kernel
  as that makes them un-usable by userspace as well as
  re-initializes them to dt defaults overriding changes which may
  have been done by bootloader commands.
- specify gpio names and initial config
- enable GPIO_HOG

v2:
 - rebase on imx/master
 - add Peng's ack tag
