If you case the CONFIG_SYS_NS16550_MIN_FUNCTIONS within a #ifdef
CONFIG_NAND_SPL you don't need the following definitions.

I was going to send a patch after this one was accepted that takes care of
the SIMPC8313 build.  Should I have sent the two of them together?  I
thought that they would be considered too different.  It would be this
below.

If you'd like, I can send this one now or you could put the new config
option inside of a #ifdef CONFIG_NAND_SPL.
