    [libata] Disable ACPI by default; fix namespace problems
    
    Not yet ready to turn on ATA ACPI by default, for either PATA or SATA.
    
    Also, rename the global-scope module parameter variable 'noacpi' to
    something more libata-specific, reducing the potential for namespace
    collision.
