drm/vmwgfx: Write the driver id registers

[ Upstream commit be576857f7f508ab6f6669d38a1c3fd129799cac ]

Driver id registers are a new mechanism in the svga device to hint to the
device which driver is running. This should not change device behavior
in any way, but might be convenient to work-around specific bugs
in guest drivers.
