Besides standard UART setup, this device needs enabling
(vendor-specific) "Enhanced Control Bits" - otherwise disabling hardware
control flow (MCR[2]) is ignored. Add appropriate quirk to the
ns16550_setup_preirq(), similar to the handle_dw_usr_busy_quirk(). The
new function act on Exar 2-, 4-, and
