    tau32-ddk.c: suppress warning about ignored attributes
    
    This driver is heavily obfuscated, and causes a -Werror warning with
    clang 18 now:
    
      sys/dev/ce/tau32-ddk.c:358:10: error: 'const' attribute on function returning 'void'; attribute ignored [-Werror,-Wignored-attributes]
        358 | ((const))nvqbt(void){__asm __volatile("repe; nop; repe; nop;"
            |          ^
    
    Supress the warning since the driver can never be fixed. Direct commit
    to stable/13, since the driver has been removed in 14.x and later.
