    ipq806x: initialize UART even when console is not enabled
    
    The ipq806x UART is based on the same universal serial port which can
    be also configured as i2c or SPI. Configuring it is not a trivial
    task, so in case the kernel wants to use earlyprintk() the port needs
    to be configured by the firmware.
    
    Invoking uart_init() when the console is not enabled causes include
    file collisions, which would require changes to more than 100 files.
    Leaving this to another day, rearranging the ipq806x driver to be able
    to invoke UART initialization function even when serial console is not
    configured.
    
    Also add a check to avoid initialization if UART has been already
    set up.
    
    BRANCH=storm
    BUG=chrome-os-partner:35364
    TEST=verified that storm console is still fully operational when
         enabled, and that the kernel boots fine to the serial console
         login prompt even if the firmware console is disabled.
