x86/tsc: Provide ART base clock information for TSC

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.
