mtd: FSMC NAND use the PrimeCell identifier macros
The FSMC actually has a standard ARM PrimeCell ID register, and the "revision" part of that register contains the thing that the code is looking at. Reuse the infrastructure from the AMBA bus abstraction and rid local defines. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
