We're going to need to tell whether we want to run with a full or limited range RGB output in multiple places in the code, so let's create a helper that will return whether we need with full range or not.

Is this ever being called from non-HDMI code? If not, I'd put an drm_WARN_ONCE around this check.
I'm not sure we need to worry about this, it's a static function in the HDMI controller driver so it can't be called from anywhere else
