In a setup with both VRR capable and non-VRR capable displays, it was so far inconsistent if the driver would allow use of VRR support or not, as "is_connector_vrr_capable" was set to whatever the capabilities of the last added drm output were. Iow. the plugging order of monitors determined the outcome. Fix this: Now if at least one display is VRR capable, the driver will treat an X-Screen as capable for VRR, plugging order no longer matters. Tested with a dual-display setup with one VRR monitor and one non-VRR monitor. This is also beneficial with the new Option "AsyncFlipSecondaries". When we are at it, also add some so far missing description of the "VariableRefresh" driver option, copied from amdgpu-ddx. Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com>
