    mediatek: add build for MT7981 RFB
    
    Add build for the MTK3943 reference board for MT7981B+MT7976C.
    
    **Hardware specification:**
    
     - SoC: MediaTek MT7981B 2x A53
     - Flash: various options
     - RAM: 256MB DDR3
     - Ethernet: 4 x 10/100/1000 Mbps via MT7531AE switch
            EITHER 1 x 10/100/1000 Mbps built-in PHY
                OR 1 x 10/100/1000/2500 Mbps MaxLinear GPY211C
     - Switch: MediaTek MT7531AE
     - WiFi: MediaTek MT7976C
     - Button: RST, WPS
    
    **Flash instructions for SPIM-NAND:**
     - write *mt7981-rfb-spim-nand-preloader.bin to 'BL2' partition
     - write *mt7981-rfb-spim-nand-bl31-uboot.fip to 'FIP' partition
     - erase 'ubi' partition
     - reset board
     - create ubootenv and ubootenv2 UBI volumes in U-Boot
     - edit environment and set bootcmd, e.g.
       setenv bootconf 'config-1#mt7981-rfb-spim-nand#mt7981-rfb-mxl-2p5g-phy-eth1'
       setenv bootcmd 'ubi read $loadaddr fit; bootm $loadaddr#$bootconf'
     - load initramfs image via TFTP:
       setenv serverip 192.168.1.254
       setenv ipaddr 192.168.1.1
       setenv bootfile openwrt-mediatek-filogic-mediatek_mt7981-rfb-initramfs.itb
       saveenv ; saveenv
       tftpboot
       bootm $loadaddr#$bootconf
     - Now use sysupgrade to write OpenWrt firmware to flash.
    
    SNFI-NAND, SPIM-NOR and eMMC all work very similar, a bootable SD card image
    is also being generated. However, as the board I've been provided only comes
    with SPIM-NAND all other boot media are untested.
