futility: update: Add "servo_noreset" opt to tell CCD not to reset
As can be seen in <https://crrev.com/c/2325190>, flashrom can take a
"custom_rst=true" parameter. Flashrom passes this on to Cr50 and
tells it not to reset. Among other things, this can be useful to work
around hardware bugs where asserting reset puts us in a bad state.
Let's add a parameter to futility can specify this mode. We'll enable
this just for "--servo" mode of flashrom and not "--ccd" mode.
Presumably we want "--ccd" to remain simple / autoconfiguring and this
is a bit more of an advanced tweak.
