[PATCH] dt-bindings: dvfs: Add support for generic performance domains

The CLKSCREW attack [0] exposed security vulnerabilities in energy management implementations where untrusted software had direct access to clock and voltage hardware controls. In this attack, the malicious software was able to place the platform into unsafe overclocked or undervolted configuration
