[coreboot] [PATCH] Make flashrom work with ST M50FW016/040 chips

[Ed Swierk]

Currently flashrom defines the ST M50FW016 and M50FW040 to use jedec
commands, but these chips don't support them, as far as I can tell.
They do support the 82802ab command set, however.

I tested this patch with an M50FW016. I don't have an M50FW040 but the
datasheet indicates the same command set as the M50FW016.
