c2kevm-nand: assorted cleanups to make it work with gftv builds.
Removed a lot of dead code in conditionals, and fixed up a bunch of
environment variables to work better with the way our builds work.
The mtd partition layout (and related update and boot_flash macros) are
still not what we want; they still read and write NOR flash, but we want to
switch to using NAND. This does work, but I recommend booting from TFTP/NFS
for early development.
