cover Add NAND to board/ti/am335x/README

The following depends on v2 of the "Improve falcon mode and am335x_evm docs" series, as that adds the README to start with.

You've already done a "nand erase.chip"... Why do you need to erase "kernel" again?

No, that's just what I get for concatening my instructions too quickly, thanks!
