nand: rename device to nand

Browse Source 
To be more informative (and consistent with flash and pld trees), change
'device' parameter name to 'nand' in NAND source files.  This change
eliminates confusing 'device->device->' instance from the code, and
it simplifies the forthcoming command handler patches.
