  ich9: add disable_s3, disable_s4, s4_val properties

PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM
functions.  Add such properties to the ICH9 chipset as well for the Q35
machine type.

S3 / S4 are not guaranteed to always work (needs work in the guest as
well as QEMU for things to work properly), and disabling advertising of
these features ensures guests don't go into zombie state if something
isn't working right.

The defaults are kept the same as in PIIX4: both S3 and S4 are enabled
by default.

These can be disabled via the cmdline:

  ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1

Note: some guests can fake hibernation by writing a hibernate image and
doing a shutdown instead of S4 if S4 isn't available; there's nothing we
can do guests to stop doing this, and this patch can't affect that
functionality.

  pci: Split pcie_host_mmcfg_map()

The mmcfg space is a memory region that allows access to PCI config space
in the PCIe world. To maintain abstraction layers, I would like to expose
the mmcfg space as a sysbus mmio region rather than have it mapped straight
into the system's memory address space though.

So this patch splits the initialization of the mmcfg space from the actual
mapping, allowing us to only have an mmfg memory region without the map.
