'Legacy Queue & Single Doorbell Support (LSDBS)' field in the controller capabilities register is supposed to report whether the legacy single doorbell mode is supported in the controller or not. But some controllers report '1' in this field which corresponds to 'LSDB not supported', but they indeed support LSDB. So let's add a quirk to handle those controllers. If the quirk is enabled by the controller driver, then LSDBS register field will be ignored and legacy single doorbell mode is assumed to be enabled always.
