[coreboot] flashrom: Winbond W83627DHG SPI, RDID 90, SST AAI & Intel D201GLY

[Peter Stuge]

Patch attached.

The wbsio driver has been tested by rphlx to work correctly for probe
and read on the Intel D201GLY board, but erase and write was not
tested since he had no easy recovery strategy in case of failure. If
anyone can test erase, write or both on a board with W83627DHG or
compatible (please add ids to wbsio_get_spibase()) I would be most
grateful. Comments, as always, appreciated.
