Trogdor: Disable the host command of EC SPI flash info
Trogdor: Disable the host command of EC SPI flash info

Flashrom first uses the host command to get EC SPI flash info. If not
there, then uses the host command to get EC chip info. The factory
process expects flashrom return the EC chip info in order to construct
a HWID.

Disable the host command of EC SPI flash info to be compliant with the
factory flow.

BRANCH=None
