gvt_err should be used only for the very few critical error message
during host i915 drvier initialization. This patch
1. removes the redundant gvt_err;
2. creates a new gvt_vgpu_err to show errors caused by vgpu;
3. replaces the most gvt_err with gvt_vgpu_err;
4. leaves very few gvt_err for dumping gvt error during host gvt
initialization.
v2. change name to gvt_vgpu_err and add vgpu id to the message. (Kevin)
add gpu id to gvt_vgpu_err. (Zhi)
v3. remove gpu id from gvt_vgpu_err caller. (Zhi)
v4. add vgpu check to the gvt_vgpu_err macro. (Zhiyuan)
v5. add comments for v3 and v4.
v6. split the big patch into two, with this patch only for checking
gvt_vgpu_err. (Zhenyu)
v7. rebase to staging branch
v8. rebase to fix branch

For the inhibit ctx, load all mmio in render mmio list
into HW by MMIO write for ctx initialization.
For the none-inhibit ctx, only load the render mmio which
is not in_context into HW by MMIO write. Skip the MMIO write
for in_context mmio as context image will load it.

Need a explicit write_vreg in TLB MMIO write handler, beside that
TLB vreg should update correspondingly following HW status to do
correct emulation.

When invalidating RCS TLB the device can enter RC6 state interrupting
the process, therefore the need for render forcewake for the whole
procedure.
This WA is needed for all production SKL SKUs.
v2: reworked putting and getting forcewake with help of Mika Kuoppala
v3: use I915_READ_FW and I915_WRITE_FW as we are handling forcewake on
in the code path

i915 core should only call functions and structures exposed through
intel_gvt.h. Remove internal gvt.h and i915_pvinfo.h.
Change for internal intel_gvt structure as private handler which
not requires to expose gvt internal structure for i915 core.
v2: Fix per Chris's comment
- carefully handle dev_priv->gvt assignment
- add necessary bracket for macro helper
- forward declartion struct intel_gvt
- keep free operation within same file handling alloc
v3: fix use after free and remove intel_gvt.initialized
v4: change to_gvt() to an inline

As different VM may configure different render MMIOs when executing
workload, to schedule workloads between different VM, the render MMIOs
have to be switched.
