    amd64 GENERIC: Switch uart hints from "isa" to "acpi"
    
    This causes these hints to be only used to wire device unit numbers
    for serial ports enumerated by ACPI but will not create ISA device
    nodes if ACPI doesn't enumerate them.  Note that IRQ hints are not
    used for wiring so have been removed.
