ACRN:DM:VDisplay: vdpy_init connection returns the supported number of vScreen

Browse Source 
Vdisplay module will create the gui_window (vScreen) based on the virtio-gpu
parameter. When virtio-gpu device tries to establish the connection with
vdisplay module, it will return the supported number of vScreen.
Then the virtio-gpu device can initialize the correct info for the guest_vm.

BTW: The number is fixed to 1.
