drivers: modem: add modem receiver (tty) driver

Modem drivers need a fast buffer-based receiver for passing data
back and forth from the UART to the driver.  This provides an
efficient configuarable driver which merely sends and receives
but doesn't process the data, that's left up to the modem driver.
