Michael S. Tsirkin 8dcf525abc acpi-build: append description for non-hotplug
As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.

I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.
As a result: before
commit 99fd437dee (enable
hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

Hardware -> PCI Cards:

  Card          Type                 Driver Installed  Slot
 *ethernet      Ethernet Controller  Yes               PCI Slot 2
  pci8086,2934  USB UHC              Yes               PCI Slot 29

  ethernet:
    Type:                 Ethernet Controller
    Driver Installed:     Yes
    MSI:                  No
    Bus:                  PCI
    Slot                  PCI Slot 2
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Slot                  PCI Slot 2
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

After commit 99fd437dee, users get:

Hardware -> PCI Cards:

  This computer doesn't contain any PCI cards. If you installed PCI
  cards, make sure they're properly installed.

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.

To fix, append description for all occupied non hotpluggable PCI slots.

One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.
