qxl-wddm-dod: Option to provide frequency data to the OS

Browse Source 
Concentrate filling of signal info in single procedure.
Fill signal info with specific or default frequency data
according to the global flag of VSync support.
Note that the state of this flobal flag must be defined only
on driver startup (based on OS version or any other information
available at DriverEntry) and can't be changed later.
