[PATCH v3 21/32] drm/i915/cx0: Add MTL+ .update_active_dpll hook

[Mika Kahola <mika.kahola@intel.com>]

Add .update_active_dpll function pointer to support
dpll framework. Reuse ICL function pointer.

v2: Add check for !HAS_LT_PHY (Suraj)
v3: Remove the incorrect !HAS_LT_PHY condition and
    check for existing dpll_mgr
