x86/jailhouse: Add infrastructure for running in non-root cell The Jailhouse hypervisor is able to statically partition a multicore system into multiple so-called cells. Linux is used as boot loader and continues to run in the root cell after Jailhouse is enabled. Linux can also run in non-root cells. Jailhouse does not emulate usual x86 devices. It also provides no complex ACPI but basic platform information that the boot loader forwards via setup data. This adds the infrastructure to detect when running in a non-root cell so that the platform can be configured as required in succeeding steps. Support is limited to x86-64 so far, primarily because no boot loader stub exists for i386 and, thus, we wouldn't be able to test the 32-bit path.
