Currently, userspace only has a way to enable/disable the entire
SBI FWFT extension. We definitely need to extend ONE_REG
interface to allow userspace save/restore SBI FWFT state. I am
sure this will happen pretty soon (probably next merge window).

At the moment, I am not sure whether userspace also needs a
way to enable/disable individual features of SBI FWFT extension.
What do you think ?
