x86, driver, tools: Pass TSC and APIC timer frequency calibration to non-root
cells
This avoids that non-root cells have to calibrate TSC and - provided
there is no TSC deadline timer support - APIC timer frequencies
themselves. Rather we now either use statically configured values from
the system configuration or, of those or 0, pick them up from the root
cell during hypervisor start. Then the values are simply forwarded via
the Communication Region to all x86 non-root cells.
This requires another patch to the root-cell Linux to export
lapic_timer_frequency for us.

inmates: x86: Add TSC deadline timer support
Use the TSC deadline timer when available. This avoids having to
calibrate the APIC timer in those cases.

Log Message:
-----------
inmates: x86: Use pre-calibrated TSC and APIC timer frequencies
The Communication Region now provides these values, so we can drop the
calibration for the inmate library. The APIC timer frequency is only
available if there is no TSC deadline timer support, but then we use the
latter anyway.

Log Message:
-----------
inmates: x86: Enhance Linux setup data structure
Expand the Jailhouse-specific setup data structure we pass to the Linux
kernel on boot by the calibrated TSC and APIC timer frequencies. Also
switch the type to a value we are going to reserve officially in the
upstream kernel, rather than using the large magic value.
Although this is a change that should normally increase the version of
the struct, we keep it untouched as we didn't release the previous
structure version yet. Specifically, there is no official kernel out
there expecting the old structure.
