Subject: [PATCH 1/2] dt-bindings: cpufreq: Add big CPU supply

The performance-controller hardware block on MediaTek SoCs is
responsible for controlling the frequency of the CPUs. As such, it needs
any CPU regulator to have been configured prior to initializing. Add a
phandle in the binding so this dependency can be described.
