[PATCH] sunxi: board: Map suniv SPI NAND boot source

[Zunyi Hu]

The Allwinner V3s (suniv) BROM returns SUNIV_BOOTED_FROM_NAND when
successfully booting from an attached SPI NAND flash. Currently, U-Boot
lacks the mapping and treats this as an invalid boot source.

Map this to SUNXI_BOOTED_FROM_SPI to ensure the boot environment and
device are correctly identified in U-Boot proper. Note that this patch
only corrects the boot source mapping; specific SPL SPI NAND loading
implementations are handled separately.

Tested-on: Allwinner V3s, SPI NAND boot.
