    arm/early-printk: add Calxeda Midway UART support
    
    With the help of the previous patches add a stanza to
    xen/arch/arm/Rules.mk to specify the UART configuration of the
    Calxeda Midway machine.
    The information has been taken from the Linux kernel's .dts file.
    This can be enabled by adding "CONFIG_EARLY_PRINTK=midway" to
    Config.mk.
