[Intel-gfx] [PATCH v2 7/7] drm/i915/bdw: sseu: Fix sseu status parsing

[Imre Deak]

Currently when checking for fused off EUs we may ignore the EU count in
an enabled slice if there is any disabled slice preceding the enabled
one (with a lower slice ID). Perhaps this can't happen in reality, but
there is no reason to have this assumption built-in, the code is clearer
without it.
