There are currently 4 methods in intel_gvt_io_emulation_ops to emulate CFG/MMIO reading/writing for intel vGPU. A possibly better scope is: add 3 more methods for vgpu create/destroy/reset respectively, and rename the ops to 'intel_gvt_ops', then pass it to the MPT module (say the future kvmgt) to use: they are all methods for external usage.
