mtd: rawnand: gpmi: move all driver code into single file 



This moves the whole driver into a single C file. The filename gpmi-lib
implies that it implements library functions, but in fact there are
several cases where functions in gpmi-lib.c call back into functions in
gpmi-nand.c. With this one has to constantly jump between those two
files, so moving it into a single file improves readability, even when
the file gets quite large.
