sunxi_nand_spl: Auto detect nand configuration parameters

Auto detect the nand configuration parameters, like the BROM does.

This allows us to get rid of various Kconfig settings, and is
necessary to support generic boards like the mk802 which have seen
many production runs with different nands.

The full blown u-boot/kernel nand driver uses the nand id to determine
this info, for the SPL we do as the BROM does and simply try a few
standard configs.

Note the table only contains configs which are known to actually be used,
rather then all the configs the BROM tries. This means that it may need
to be updated in the future as we add support for nand on more boards.
