This commit add support for 96Boards Dragonboard410C. It is board based on APQ8016 Qualcomm SoC, complying with 96boards specification. Features (present out of the box): - 4x Cortex A53 (ARMv8) - 2x USB Host port - 1x USB Device port - 4x LEDs - 1x HDMI connector - 1x uSD connector - 3x buttons (Power, Vol+, Vol-/Reset) - WIFI, Bluetooth with integrated antenna - 8GiB eMMC
U-Boot boots chained with fastboot in 64-bit mode. For detailed build instructions see readme.txt in board directory.

Changes in v3: - readme: Added info on how to enter fastboot mode and that dtbTool is also part of skales. Added more explanation on image generation. - head: Add comment why it's needed, drop MZ EFI signature that makes no sense on this particular SoC, fix confusing entry point name (+update .lds file)
Changes in v2: - Renamed CONFIG_DM_SPMI -> CONFIG_SPMI - Removed extra enter in dragonboard file - Added ULPI* to defconfig - Added MAINTAINERS to board - Cleaned up config file - use distro defaults/environment: - Dropped multiple CONFIG_CMD* and other CONFIG_* - Added distro env/config - Dropped old boot commands - Split dts - pm8916_gpio entries are taken directly from Linux Dragonboard dts; Add handles for u-boot in -uboot.dtsi; They will be removed once gpio drivers are converted to pinctrl. - Renamed some pmic nodes, fixed dragonboard.c to find them properly. - Added header and converted comments to c98-style in head.S - Print error if pmic gpio node is not found.
Changes in v1: - Add better help for dragonboard - Move static structures to board_prepare_usb - Add DM_SPMI to defconfig
