If the gen68360 BSP supported more serial ports, they would likely
have been registered by  the console driver.  It only
registers a single serial port.  Often a single serial port/console
driver will register multiple serial ports if it can support them
all.

AFAIK there is only a single serial port supported so there are
no more device drivers in the gen68360.
