[Intel-gfx] [PATCH 4/4] drm/i915: Unmask and enable master error interrupt on gen2/3

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

For whatever reason we only unmask and enable the master error
interrut on gen4. With the EIR handling fixed let's do that
on gen2/3 as well.
