drm/i915/display: Add glk_cdclk_table

Commit 736da811 ("drm/i915: Use literal representation of cdclk
tables") pushed the cdclk logic into tables, adding glk_cdclk_table but
not using yet:

drivers/gpu/drm/i915/display/intel_cdclk.c:1173:38: error: ‘glk_cdclk_table’ defined but not used [-Werror=unused-const-variable=]
