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).
