drm/i915/guc: Don't enable GuC/HuC in auto mode on pre-Gen11
We are about to change default setting of "enable_guc" modparam from 0(disabled) to -1(auto). As we only want to turn on GuC/HuC on Gen11+, keep it off for older gens. Note that it would be still possible to enable GuC/HuC on these old platforms using explicit "enable_guc=2" modparam.
