Merge u-boot/master into u-boot-ti/master
In master we had already taken a patch to fix the davinci GPIO code for
CONFIG_SOC_DM646X and in u-boot-ti we have additional patches to support
DA830 (which is CONFIG_SOC_DA8XX && !CONFIG_SOC_DA850). Resolve these
conflicts manually and comment the #else/#endif lines for clarity.
Conflicts:
arch/arm/include/asm/arch-davinci/gpio.h
drivers/gpio/da8xx_gpio.c
