arm-common: Force enabling the clock gate of the debug console
Enable the clock gate of the debug console, even in the case it has been turned
off i.e. because the root cell is not using the UART.

driver: Account for upcoming changes to device tree overlay API
In 4.15, of_overlay_create and of_overlay_destroy were refactored to
of_overlay_apply and of_overlay_remove, also changing the parameters and
return values. Prepare for this change while staying compatible with
older kernels.

inmates, tools: Avoid warnings of objtool
Latest 4.15 kernel comes with the ORC unwinder and, along that, a
number of build-time checks on object files. These are tailored for the
kernel and do not go well with both our inmates and the userspace tools,
e.g.:
.../jailhouse.o: warning: objtool: read_file() falls through to next function
parse_cell_id()
.../jailhouse.o: warning: objtool: help() falls through to next function
open_dev()
.../jailhouse.o: warning: objtool: open_dev() falls through to next function
cell_simple_cmd()
(because of lacking knowledge about no-return functions)
Disable them for x86 inmates, currently the only affected arch, and the
tools.

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.

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.

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.
