This restructures the device structs and now utilizes the new driver initialization model. This is another step towards converting the serial driver to the new driver model. Note that the serial driver does not initialize the hardware unless it is being used by another driver. The configuration of the serial port needs to be done by the driver utilizing the port (e.g. baud rate, interrupt priority, etc.). Therefore, some serial ports are declared but not exactly configured. Also note that the UART console is being initialized at the same time as the serial port. This will be removed in future patch, so the UART console driver will do its own initialization.
