The situation is similar to the existing bindings for MSM8974: there is an additional "mss" power domain that must be voted for while starting up the remote processor. The difference is that on MSM8974 the power domain is represented as a regulator (firmware expects specific voltage) while on MSM8953 it is represented as power domain (firmware expects performance state instead of voltage). Handle this difference by adding the "mss" power domain as optional third item, and then restrict it (and make it required) only when using the MSM8953 compatible.
