Instead of creating virtual regulators I would be strongly in favor of reviving the voltage-domain work. That would allow us to push all those voltage dependencies we have seen on various SoCs into the domain handling code and don't care about it in the drivers.
In that case cpufreq-dt wouldn't control a regulator directly, but request a specific voltage from the domain the CPUs are located in and those in turn would control the regulators supplying them.
I agree that it would be the right approach but who is going to do that stuff ?
I think until the time we revive the voltage-domain stuff we need to support mediatek's driver. And probably a virtual regulator is the best approach unless someone else comes up with another idea.
