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 Signed-off-by: Tim Harvey <tharvey@gateworks.com> Acked-by: Peng Fan <peng.fan@nxp.com>
