[U-Boot] [PATCH 2/2] rockchip: rk3188: Add Radxa Rock board

[Heiko Stuebner <heiko@sntech.de>]

The Rock is a RK3188 based single board computer by Radxa.
Currently it still relies on the proprietary DDR init and
cannot use the generic SPL, but at least is able to boot
a linux kernel and system up to a regular login prompt.
