arm-trusted-firmware-mediatek: add ATF builds for MT7622

Browse Source 
ATF bl2 comes in 4 variants for MT7622 depending on the boot media:
 * nor
 * snand
 * emmc
 * sdmmc

Additional binary headers needed for emmc and sdmmc are downloaded as
well and provided along with bl2*.bin and bl31.bin to allow building
images including ATF for MT7622.
