x86: Relocate parking code page
This step prepares for configurable cell reset addresses. In order to
enable them, we need a stable parking code address so that we do not
need to generate per-cell mappings for this purpose.
Simply place the parking loop at address 0. Use a regular SIPI vector 0
for resetting the affected CPUs. This means on Intel that we have to
issue the DEBUGCTL reset separately in vcpu_park because we no longer
take the APIC_BSP_PSEUDO_SIPI path.

x86, configs: Make CPU reset address configurable
Analogously to ARM, this makes the reset address of x86 CPUs definable
via jailhouse_cell_desc.cpu_reset_address. In order to keep the existing
demo inmates alive, all related config files define cpu_reset_address to
0xffff0 which was hard-coded into the hypervisor so far.

x86: Export PCI mmconfig base address to Linux inmates
In order to access the PCI express extended configuration space, a linux
inmate needs to have access to the PCI mmconfig base address. As inmates
doesn't have access to this information using ACPI, we need to export it
using the cell comm_region.
Note that the updates in Linux kernel used as inmate are also necessary
in order to use the exported value as the PCI mmconfig base address.

x86: Fix general protection fault on restoring TR
arch_cpu_restore can run concurrently on multiple CPUs, but our
modifications to the GDT in order to reload Linux TR requires that a
couple of instructions run atomically. Namely, loading TR will set the
busy flag in the descriptor again which may race with another CPU just
trying to load from that descriptor as well. Putting everything under a
spinlock resolves the race.
The effect of this bug were sporadic general protection faults (#13)
while disabling Jailhouse or when enabling it failed.

x86: Add support for PAE guest paging mode
This completes the guest paging support with the last missing mode: PAE.
While most guests should not use this legacy mode anymore, at least
Zephyr does. Moreover, supporting this last missing mode allows to drop
the error handling around vcpu_get_guest_paging_structs.
The implementation is complicated on Intel because these CPUs cache the
page directory pointer table in registers, and we can't use the generic
reading from guest memory. In contrast, AMD performs no such caching.
Therefore, we have to use a vendor-specific get_entry handler for the
top level paging.

Do not stop a cell CPU that accesses an IOAPIC redirection table entry

It allows guests like Linux to keep their usual IOAPIC initialization
code as-is which may first of all masks all pins of the chip.
