[MTD] dataflash OTP support
Now that we can tell when we have one of the newer DataFlash chips, optionally expose the 128 bytes of OTP memory they provide. Tested on at45db642 revision B and D chips. Switch mtdchar over to a generic HAVE_MTD_OTP flag instead of adding another #ifdef for each type of chip whose driver has OTP support.
