    arm: Drop deprecated early printk platform options
    
    The predefined configurations for early printk have been deprecated for
    a sufficient amount of time. Let's finally remove them.
    
    Note:
    In order not to lose these predefined configurations, I wrote a wiki
    page: https://wiki.xenproject.org/wiki/Xen_on_ARM_Early_Printk
