soc/intel/cnvi: Add HotPlugSupportInD3 Property

Browse source 
Add a DSD with the HotPlugSupportInD3, as when it RTD3, the device
will appear as not-present. This will cause Windows to constantly
try to enable it, causing an endless loop of the device becoming
visible.

Test=build and boot `starlabs/starlite_adl`, check CNVi is always
visible in device manager.
