Peter Grehan 332cda07c0 Complete polled-mode operation by using a callout if the device will be ... used in polled-mode. The callout invokes uart_intr, which rearms the timeout. Implemented for bhyve, but generically useful for e.g. embedded bringup when the interrupt controller hasn't been setup, or if it's not deemed worthy to wire an interrupt line from a serial port.
