Add support for Numonyx N25Q016 and N25Q032
The 32Mb version has 1.8V and 3.0V versions, the smaller one 1.8V only (or Numonyx/Micron forgot to publish it). Another difference is that the 16Mb chip has 32 kB subsectors (erase opcode 0x52). As long as there are no funky configurations like for the 128Mb chips, we got the smaller parts covered with this change. Corresponding to flashrom svn r1615.
