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.

inmates, configs, docs: x86: Locate inmates at address 0
This simplifies the startup code and avoids having to specify the load
address explicitly, aligning x86 with ARM.

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: Fix arch_cpu_restore for PCID enabled systems
Reorder reloading of cr3 and cr4 in case the latter enables PCID (which
Jailhouse does not use) and cr3 should be fully evaluated under that
feature.
Fixes a protection fault when disabling Jailhouse on PCID-enabled
systems (since kernel 4.14).
