[PATCH qemu 08/12] m25p80: add mx25l25635f chip

[Cédric Le Goater]

The Macronix chip mx25l25635f used on some OpenPower boxes is very
similar to the mx25l25635e. They share the same JEDEC identifier but
the WRSR instruction requires 2 bytes in the mx25l25635f case.

This patch introduce a new chip to prevent some warnings on guests
identifying JEDEC 0xc22019 as a MX25L25635F chip. OpenBMC is one them.

 This is may not be the best way to distinguish these chips. Adding a
 flag in the FlashPartInfo would be better ?
