    xen/arm: Rename all early printk macro
    
    We are going to move the generation of the early printk macro into
    Kconfig. This means all macro will be prefix with CONFIG_. We do that
    ahead of the change.
    
    We also take the opportunity to better name some variables, which are
    used by only one driver and wouldn't make sens for other UART driver.
    Thus,
        - EARLY_UART_REG_SHIFT became CONFIG_EARLY_UART_8250_REG_SHIFT
        - EARLY_PRINTK_VERSION_* became CONFIG_EARLY_UART_SCIF_VERSION_*
    
    The other variables are change to have the prefix CONFIG_EARLY_UART_
    when they change a parameter of the driver. So we have now:
        - CONFIG_EARLY_UART_BAUD_RATE
        - CONFIG_EARLY_UART_BASE_ADDRESS
        - CONFIG_EARLY_UART_INIT
