drm/i915/display: Enable/disable casf 



Call intel_casf_enable and intel_casf_disable
in atomic commit path to enable and disable casf.
Call intel_casf_update_strength to only update
the desired strength value.

v2: Introduce casf_enable here.[Ankit]
v3: Use is_disabling in casf_disabling.[Ankit]
v4: Swap old_state and new_state param.[Ankit]
v5: In disable fn move win_sz after sharpness_ctl.
v6: Rebase and update commit message.
