[Intel-gfx] [PATCH] drm/i915: s/MI_STORE_DWORD_IMM_GEN8/MI_STORE_DWORD_IMM_GEN4/

[ville.syrjala at linux.intel.com]

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

MI_STORE_DWORD_IMM length has been the same ever since gen4. Rename
the define to avoid potential confusion if someone tries to use this
on pre-gen8.

Also correct the comment on MI_MEM_VIRTUAL bit. It's present on 945,g33
and 965 only.
