If BXT pooled EU enable, the 3*6 EUs is split into 2 pooled, so change the sub slice to 2. For min no. of eu in pool, only affact fused down 2*6 BXT devices, because beignet don't support these devices now, add assert only. assert. This patch is based on kernel patch: https://patchwork.freedesktop.org/series/8200/ Thanks Arun.
