Julia Suvorova 211afe5c69 hw/i386/acpi-build: Deny control on PCIe Native Hot-plug in _OSC 
There are two ways to enable ACPI PCI Hot-plug:

        * Disable the Hot-plug Capable bit on PCIe slots.

This was the first approach which led to regression [1-2], as
I/O space for a port is allocated only when it is hot-pluggable,
which is determined by HPC bit.

        * Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC
          method.

This removes the (future) ability of hot-plugging switches with PCIe
Native hotplug since ACPI PCI Hot-plug only works with cold-plugged
bridges. If the user wants to explicitely use this feature, they can
disable ACPI PCI Hot-plug with:
        --global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off

Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug
instead of PCIe Native.
