- Include minimum header insted in intel_gvt_mmio.c (Jani)

v8:
- Use SPDX header in the intel_gvt_mmio_table.c
- Reference the gvt.h with path. (Jani)
- Add a missing fix on mmio emulation path during the debug.
- Fix a building problem on refreshed gvt-staging branch. (Christoph)

v7:
- Keep the marcos of device generation in GVT-g. (Christoph, Jani)

v6:
- Move the mmio_table.c into i915. (Christoph)
- Keep init_device_info and related structures in GVT-g. (Christoph)
- Refine the callbacks of the iterator. (Christoph)
- Move the flags of MMIO register defination to GVT-g. (Chrsitoph)
- Move the mmio block handling to GVT-g.

v5:

v4:
- Fix the errors of patch checking scripts.
