faft: Support EC write protect on non-Chrome-EC devices
On non-Chrome-EC devices, we use flashrom as a single interface to set
write protection for different chips. This CL supports this function
such that we can run suite:faft_ec_wp on non-Chrome-EC devices.
BUG=chrome-os-partner:15835
TEST=mock the flashrom in DUT and run suite:faft_ec_wp, see it executed.
