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".

Changes in v6:
- Added MAINTAINERS file.
- Removed project-specific configs/vocore2_defconfig_ENV_IN_FAT.
- Removed guard for SPL Serial definitions in include/configs/vocore2.h.
- Removed Baudrate Table definition in include/configs/vocore2.h.
- Moved board-specific DTS settingsto arch/mips/dts/vocore_vocore2.dts.
- Added UART2 pin definitions to arch/mips/dts/vocore_vocore2.dts.
- Removed unused mmc pin definition from arch/mips/dts/vocore_vocore2.dts.
- Added select of SPL_UART2_SPIS_PINMUX in board choice.
- Updated configs/vocore2_defconfig.
Changes in v5:
- Removed unneeded (and wrong) UART2 initialization in board.c
- Added network setup.
- Removed project-specific code.
- Move back environment to SPI NOR.
- Changes to environment default settings.
- Rebase on current u-boot-mips/testing.
Changes in v4:
- Reverted some overzealous DTS cleaning.
- Added support for bootcount.
Changes in v3:
- based on top of Weijie Gao patchset: "[v3,xx/20]Refactor the architecture parts of mt7628"
Changes in v2:
Removed some dead code
Changed Author to my full name (no nick)
Removed unwanted fixup to .dts generation (not my call).
Fixed commit message
Fixed various variables/filenames to include Vendor name
Changed Vendor name (Vonger -> Vocore)
