drm/i915/pm: Make the wm parameter of print_wm_latency a pointer

Browse Source 
This fixes the following build error with GCC 11:

    In function ‘snb_wm_latency_quirk’,
        inlined from ‘ilk_setup_wm_latency’ at drivers/gpu/drm/i915/intel_pm.c:3109:3,

          |             ^~~~~~~~~~~~~~~~~~~~~~

As far as I can tell, we don't actually need 8 elements except on SKL
and that uses dev_priv->wm.skl_latency which has enough.
