split NAND driver handling into nand/driver.[ch]

This work parallels the NOR directory, encapsulating the NAND drivers
into a separate file.  This takes an extra step by encapsulating the
type of data structure used to manage the drivers, allowing it to be
changed from an array to a dynamic list in the future.
