[Intel-gfx] [PATCH v11 2/6] drm/i915: Implement dynamic GuC WOPCM offset and size calculation

Hardware may have specific restrictions on GuC WOPCM offset and size. On Gen9, the value of the GuC WOPCM size register needs to be larger than the value of GuC WOPCM offset register + a Gen9 specific offset (144KB) for reserved GuC WOPCM. Fail to enforce such a restriction on GuC WOPCM size will
