Add subclass for virtio-console pci device. Without the subclass, the device may be probed by 8250_pci serial driver, and lead to segment fault in acrn-dm. This issue appears when running debian as Guest OS. But there is a potential issue, if a new serial driver, which use class and subclass same as virtio-console, the problem may still trigger. Need to fix it case by case. Tracked-On: #3615 Signed-off-by: Conghui Chen <conghui.chen@intel.com> Acked-by: Yin Fengwei <fengwei.yin@intel.com>
