drm/i915: Disable framebuffer compression for i915 driver in VM
Framebuffer compression is disabled when driver detects it's
running in a Intel GVT-g enlightened VM, because FBC is not
emulated and there is no stolen memory for a vGPU.
v2:
take Chris' comments:
- move the code into intel_update_fbc()
v4:
take Tvrtko's comments:
- rebase the code into intel_fbc_update()
