drm/amd/amdgpu: Only reserve vram for firmware with vega9 MS_HYPERV host.

Browse source 
driver loading failed on VEGA10 SRIOV VF with linux host due to a wide
range of stolen reserved vram.
Since VEGA10 SRIOV VF need to reserve vram for firmware with windows
Hyper_V host specifically, check hypervisor type to only reserve
memory for it, and the range of the reserved vram can be limited
to between 5M-7M area.
