meta-facebook: minerva: enable chassis power cycle

Because CMM is without any host, we use the "Chassis" of the phosphor-state-manager which the chassis0 to indicate the "CMM sled power cycle" to control the CMM board only and the chassis1 to indicate the "CMM chassis power cycle" to control the entire system including CMM, compute, and network blades.
