1. Remove unportable O and D format specifiers
2. Fix X format specifier to print upper-case hex characters
3. Fix d format specifier to print -ve numbers
4. Fix handling of int vs. long (although not actually an issue
for the i386 compile target)
5. Don't use the antiquated C 'register' type attribute.

hvmloader is responsible for - amoungst other things - initialising
the PCI device BARs prior to loading the guest BIOS. The previous
code only probed for devfn up to 128. The lower 3 bits are function
IDs so this meant that only devices in slots 0-15 were actually being
initialized.

As part of the QEMU/Xen merge, this patch comes to change the value of
sleep states and add some information in the PCI registers to match the
implementation of the BIOS of QEMU.
It also does a hypercall (HVM_PARAM_ACPI_IOPORTS_LOCATION) that tell the
Xen to use the new Port I/O instead of the old one.
[ Also, in this patch, update QEMU_TAG to the qemu-xen revision
with the corresponding qemu change. -iwj ]

When graphics card is assigned to a guest as a secondary VGA,
without gfx_passthru and emulated VGA is the primary VGA,
hvmloader misreads gfx_passthru is specified if VGA device is
found after the emulated VGA.
This patch fix this issue. If emulated VGA is found, hvmloader
preserves it and loads vgabios of the emulated VGA.

Make build.c dependency on ssdt_{pm,tpm}.h explicit, else they can be
built in the wrong order.
Also, improve naming of target DSDT structures, and specify -p option
to iasl so that all generated files for a given target have
target-unique names, hence build can proceed safely in parallel.
