The GeekBox contains an MXM3 module with a Rockchip RK3368 SoC.
Some connectors are available directly on the module.
This adds initial support, namely serial and USB.

v1 -> v2:
* Dropped rk3368-geekbox.dtsi. rk3368-geekbox-landingship.dts can
#include "rk3368-geekbox.dts" just fine, when leaving out /dts-v1/;.
* Revisited always-on / boot-on for PMIC regulator nodes. (Heiko)
* Switched pmic-sleep from RK_FUNC_GPIO to RK_FUNC_2. (schematics)
