Ville Syrjälä 2d1b505647 drm/i915: Always use cpp==4 for FW_BLC_SELF on 915GM/945GM
Bspec says:
"FW_BLC_SELF
 ...
 Programming Note [DevALV] and [DevCST]: When calculating watermark
 values for 15/16bpp, assume 32bpp for purposes of calculation using
 the high priority bandwidth analysis spreadsheet."

Let's do that.

Perhaps this might even help with the problem that resulted in
commit 2ab1bc9df0 ("drm/i915: Disable self-refresh for untiled fbs on i915gm")
