x86/tsc: Provide ART base clock information for TSC
The core code provides a new mechanism to allow conversion between ART and
TSC. This allows to replace the x86 specific ART/TSC conversion functions.
Prepare for removal by filling in the base clock conversion information for
ART and associating the base clock to the TSC clocksource.
The existing conversion functions will be removed once the usage sites are
converted over to the new model.

x86/kvm, ptp/kvm: Add clocksource ID, set system_counterval_t.cs_id
Add a clocksource ID for the x86 kvmclock.
Also, for ptp_kvm, set the recently added struct system_counterval_t member
cs_id to the clocksource ID (x86 kvmclock or ARM Generic Timer). In the
future, get_device_system_crosststamp() will compare the clocksource ID in
struct system_counterval_t, rather than the clocksource.
For now, to avoid touching too many subsystems at once, extract the
clocksource ID from the clocksource. The clocksource dereference will be
removed once everything is converted over..

x86/tsc: Add clocksource ID, set system_counterval_t.cs_id
Add a clocksource ID for TSC and a distinct one for the early TSC.
Use distinct IDs for TSC and early TSC, since those also have distinct
clocksource structs. This should help to keep existing semantics when
comparing clocksources.
Also, set the recently added struct system_counterval_t member cs_id to the
TSC ID in the cases where the clocksource member is being set to the TSC
clocksource. In the future, get_device_system_crosststamp() will compare
the clocksource ID in struct system_counterval_t, rather than the
clocksource.
For the x86 ART related code, system_counterval_t.cs == NULL corresponds to
system_counterval_t.cs_id == CSID_GENERIC (0).

time: Add mechanism to recognize clocksource in time_get_snapshot
System time snapshots are not conveying information about the current
clocksource which was used, but callers like the PTP KVM guest
implementation have the requirement to evaluate the clocksource type to
select the appropriate mechanism.
Introduce a clocksource id field in struct clocksource which is by default
set to CSID_GENERIC (0). Clocksource implementations can set that field to
a value which allows to identify the clocksource.
Store the clocksource id of the current clocksource in the
system_time_snapshot so callers can evaluate which clocksource was used to
take the snapshot and act accordingly.
