    x86: 64: enable pci hotplug and acpipnp
    
    This will allow dynamically adding/removing at least virtio-net pci
    devices which are quite the norm in cloud environment with QEMU/KVM
    
        netdev_add bridge,id=wan2,br=br-wan,helper=/home/yousong/.usr/libexec/qemu-bridge-helper
        device_add virtio-net-pci,id=devwan2,netdev=wan2,mac=11:22:33:22:11:00
    
    The config was formed by selecting target x86/64 first, then select
    CONFIG_HOTPLUG_PCI and CONFIG_HOTPLUG_PCI_ACPI with
    
        make kernel_menuconfig CONFIG_TARGET=subtarget
    
    The following text tries to explain how the current config was formed
    
     1. CONFIG_PCI_LABEL and CONFIG_ATA_PIIX were removed because they were
        already enabled in x86 platform config
     2. CONFIG_ATA_SFF was removed because it was enabled in generic config
     3. CONFIG_NLS was removed because it will be selected by CONFIG_PCI_LABEL
