From: Anthony PERARD <anthony.perard@xxxxxxxxxx>
As part of the QEMU/Xen merge, this patch comes to change the IO Port
addresses, the value of sleep states and add some information in the PCI
registers to match the implementation of the BIOS of QEMU.
This patch must be applied at the same time with another patch for the
piix4acpi of qemu-xen.
Signed-off-by: Anthony PERARD <anthony.perard@xxxxxxxxxx>
