uboot-mediatek: sync spi-nand driver with SDK

Browse Source 
When adding new router support, I found that uboot
could not recognize flash: "unknown raw ID xxx".

Sync SPI-NAND driver for mediatek to fixes this:
 * Add support for Winbond W25N01KV 1Gbit chip.
 * Add support for Etron SPI-NAND chip.
