Changbin Du 4671ea2041 drm/i915/gvt: Optimize ring siwtch 2x faster again by light weight mmio access wrapper 
The I915_READ/WRITE is not only a mmio read/write, it also contains
debug checking and Forcewake domain lookup. This is too heavy for
GVT ring switch case which access batch of mmio registers on ring
switch. We can handle Forcewake manually and use the raw
i915_read/write instead. The benefit from this is 2x faster mmio
switch performance.
         Before       After
cycles  ~550000      ~250000

v2: Use existing I915_READ_FW/I915_WRITE_FW macro. (zhenyu)
