arm: Add PSCI v0.1 support as provided by U-Boot
Upstream U-Boot will continue to offer only a PSCI v0.1 interface. To
make us independent of patches, add the IDs for CPU_OFF and CPU_ON to
the dispatcher. Those functions are practically compatible between 0.1
and 0.2.

driver: Account for removal of cpumask_scnprintf
4.0 provides cpumask formatting via the %*pb format specifier.
cpumask_scnprintf was removed. So we need to implement both variants
for staying compatible with older kernels.

driver: Update CR4 on x86 after hypervisor enabling/disabling
Linux gained CR4 shadowing in 4.0: it now keeps a software copy of the
mm's CR4 state and only write updates on changes. But this also means it
will miss changes to this register when enabling or disabling Jailhouse.
That will cause sporadic access violations or false reporting of
virtualization-busy CPUs on Jailhouse enable.
Fix it by re-initializing the shadow on x86 after returning from the
hypervisor entry or the disable command. We are still protected from
interrupts at that point, so nothing can leak to other tasks.

arm: Add support for Jetson TK1 board
The Jetson TK1 board uses the NVIDIA K1 processor, namely the Tegra124.
The CPU has 4 Cortex-A15 cores and a low-power companion core which we
do not support, though. This SoC apparently contains all virtualization
features we need, specifically full SMMU coverage of I/O devices.
For now, board support is similar to the Banana Pi: We replicate UART
and SMP/PSCI features and add some configs (only one for both demos as
only one UART is accessible).
Open issues, besides adding SMMU support, are managing the access to the
so-called legacy Interrupt controller of the K1 (an additional stage
between devices and GIC) and sub-page access control to various devices
(same issue as with the Allwinner A20). Also, it becomes clearer than
ever that we urgently need to refactor the UART layer as well as
SMP/PSCI support to reduce duplications.

arm: Power off non-root CPUs before shutting down the hypervisor
When handing back a CPU previously used by a non-root cell directly to
Linux during hypervisor shutdown, we have to power it off when Linux is
using PSCI. Otherwise, the CPU_ON command issued by Linux later on to
gain control over the CPU again may not work as expected.
All our supported boards except for the Versatile Express come with PSCI
support. Try both v0.2 and the v0.1 encoding of U-Boot for CPU_OFF. At
least one of them must work.
The GICC is not reset by the power-down, thus we have to reset it shut
it down explicitly.
