Rename nand.h as flash/nand/core.h, chase consumers.  The public APIs
need to be sorted out with imp.h, but this allows other changes to
begin improving the separation between policy and mechanism.

Moves #include <target/target.h> and #include "driver.h" into the
internal headers or source files, removing it from <flash/nand/core.h>.

Moves commands into nand/tcl.c and core implementation to 'nand/core.c'
and 'nand/fileio.c'.  Eliminates 'flash/nand.c'.

Adds 'nand/imp.h' to share routines between TCL commands and core.
