    drivers/pc80: Rework normal / fallback selector code
    
    Per IRC and Gerrit discussion, the normal / fallback
    selector code is a rather weak spot in coreboot, and
    did not function correctly for certain use cases.
    
    Rework the selector to more clearly indicate proper
    operation, and also remove dead code.  Also tentatively
    abandon use of RTC bit 385; a follow-up patch will
    remove said bit from all affected mainboards.
    
    The correct operation of the fallback code selector
    approximates that of a power line recloser, with
    a user option to attempt normal boot that can be
    cleared by firmware, but never set by firmware.
    Additionally, if cleared by user, the fallback
    path should always be used on the next reboot.
