This patch adds a20_nandread command. It is simple function utilizing

This stuff should really be integrated with cmd_nand.c rather than
adding an adhoc SoC specific interface.
I want to go even further and I see that this really needs to be integrated
with the blkdev code so that one can just do:
ls nand 0:1
And things will just work, these way we can also just have the standard
boot cmds from config_distro_bootcmd.h work rather then needing special
nand boot commands.
