    arm-trusted-firmware-mediatek: add MT7988 BL2 DDR4 images
    
    Other than most boards with DDR4 the ASUS ZenWiFi BT8 cannot use the
    "comb" DDR calibration option and needs only the "ddr4" option set
    instead.
    
    Build TF-A SPIM-NAND with UBI as well as to boot from RAM with
    mtk_uartboot for MT7988 with DDR4 RAM.
