[coreboot] FLASHROM: Add support for M25P16.RES

i've tried using flashrom for reading the SPI Flash of my Thinkpad X60s.
It seems like it is using the (yet) unsupported M25P16.RES.
I've added the few lines required to get it working, and at least
reading the Flash works. Haven't tried writing the Flash (yes, i know
about the risk regarding EC and friends) ;-)
