Please use the minimum size 16MB GPMC range here, NAND only
has few registers addressable unlike NOR that actually uses the
whole range.

Then here map the true size of the NAND device IO register area.

BTW, we should do the similar changes to other files so we can
unify the GPMC partitioning a bit. But that's unsafe to do until 
we have fixed the issue of mapping GPMC devices to a different
location from the bootloader location.
