MIPS: Octeon: Use device tree to register serial ports.
Switch to using the device tree to register serial ports.
Add all the ports with compatible = "cavium,octeon-3860-uart". Octeon serial
ports have their own device type, required port flags, and I/O
functions, so using of_serial.c is not indicated.
We need to do this as late_initcall, as the 8250 driver must be
initialized before we add any ports. 8250 initialization is done at
device_initcall time.
The OCTEON_IRQ_UART{0,1,2} symbols are removed as they are now unused
and interfere with irq_domain used by the device tree code.
