ChromeOS: Drop filling ECFW_RW/RO state in CNVS
This field was never meant to be filled out by coreboot, because it
can't know what the right value for this will be by the time the OS
is running, so anything coreboot could fill in here is premature.
This field is only read by the chromeos-specific `crossystem` utility,
not by kernel code, so if one does not run through depthcharge there'll
be many more broken assumptions in CNVS anyway.
