Subject: [PATCH] nand: rename device to nand

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.
