flashchips: Add support for Fudan SPI flash chips
flashrom-stable: Found additional info on Github:
Code is taken from existing PATCH by Stefan Tauner stefan.tauner@alumni.tuwien.ac.at
https://mail.coreboot.org/pipermail/flashrom/2016-June/014672.html
With the only change being the Manufacture ID being changed
from 0x04h to 0xA1h.
I have only tested it with FM25F005 and it seems to work.
