drm/i915/vrr: Set vrr.enable for VRR TG with fixed_rr 



For platforms that enable VRR TG only for variable timings, the
VRR_CTL.VRR_ENABLE bit indicates VRR is active. For platforms that
always have VRR TG enabled, the VRR_CTL.VRR_ENABLE bit indicates VRR
is active only when not in fixed refresh rate mode.
