drm/i915/pm: Make the wm parameter of print_wm_latency a pointer
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,
inlined from ‘intel_init_pm’ at drivers/gpu/drm/i915/intel_pm.c:7695:3:
drivers/gpu/drm/i915/intel_pm.c:3058:9: error: ‘intel_print_wm_latency’ reading 16 bytes from a region of size 10 [-Werror=stringop-overread]
3058 | intel_print_wm_latency(dev_priv, "Primary", dev_priv->wm.pri_latency);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/i915/intel_pm.c: In function ‘intel_init_pm’:
drivers/gpu/drm/i915/intel_pm.c:3058:9: note: referencing argument 3 of type ‘const u16 *’ {aka ‘const short unsigned int *’}

2995 | static void intel_print_wm_latency(struct drm_i915_private *dev_priv,
| ^~~~~~~~~~~~~~~~~~~~~~
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.
