Micron N25Q128 has two types of flash:

 - One is for 1.8v supply voltage, prefixed with "n25q128a11" and the jedec
   code is 0x20bb18.

 - Another is for 3v supply voltage, prefixed with "n25q128a13" and the jedec
   code is 0x20ba18.

So modify the original type info and add another type for Micron N25Q128.
