Merge branch 'newsoc/andes' into soc/newsoc

Patches from Ben Zong-You Xie <ben717@andestech.com>:

The Voyager is a 9.6” x 9.6” Micro ATX form factor development board
including Andes QiLai SoC. This patch series adds minimal device tree
files for the QiLai SoC and the Voyager board [1].

Now only support basic uart drivers to boot up into a basic console. Other
features will be added later.
