drm/i915/vrr: Stop writing VRR_CTL_IGN_MAX_SHIFT for MTL onwards
According to Bspec VRR_CTL_IGN_MAX_SHIFT doesn't exist for MTL and
onwards. On LunarLake and onwards Bit 30 is "Mask Block PkgC" instead. Stop
writing the bit for MeteorLake and onwards
v2: "Ignore Max Shift" bit doesn't exist on MeteorLake either
Bspec: 50508, 68925
