drm/i915/gvt: factor out tlb and mocs register offset table Factor out tlb and mocs register offset table to fix the issues reported by klocwork, #512 and #550. Mostly, the reason why the klocwork reports these problems is because there can be possbilities for platforms, which have more rings than the ring offset table, to take the dirty data from the stack as the register offset. It results to a random HW register offset writting in this scenairo when doing context switch between vGPUs. After the factoring, the ring offset table of TLB and MOCS should be per platform. v2: - Enable TLB register switch for GEN8.
