mediatek: mt7622: add spi-nand support for bananapi bpi-r64

Browse Source 
Some of bpi-r64 boards have serial NAND attached to SPI bus.
Add SD card image support for installing openwrt to it.
Default to nand upgrade if root device is not mmc block device.

Separate preloader and uboot images for snand are generated.
