drm/i915: Initialize num_scalers for skl and glk too

After commit 1c74eeaf16b8 ("drm/i915: Move number of scalers initialization to
runtime init"), scalers are not initialized properly for skl and glk
since num_scalers is left as 0 for those platforms.

Fixes: 1c74eeaf16b8 ("drm/i915: Move number of scalers initialization to runtime init")
