mips: Add support for SoM "VoCore2".
Small patch to add support for VoCore/VoCore2 board. VoCore is open hardware and runs OpenWrt/LEDE. It has WIFI, USB, UART, 20+ GPIOs but is only one inch square. It will help you to make a smart house, study embedded system or even make the tiniest router in the world. Details about this SoM can be found at "https://vocore.io/v2.html".
