All Imagination GPUs use three clocks: core, mem and sys. All reasonably modern Imagination GPUs also support a single-clock mode where the SoC only hooks up core and the other two are derived internally. On GPUs which support this mode, it is the default and most commonly used integration. Codify this "1 or 3" constraint in our bindings and hang the specifics off the vendor compatible string to mirror the integration-time choice.
