From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
The core code provides a mechanism to convert the ART base clock to the
corresponding TSC value without requiring an architecture specific
function.
All what is required is to store the ART clocksoure ID and the cycles
value in the provided system_counterval structure.
Replace the direct conversion via convert_art_ns_to_tsc() by filling in
the required data.
No functional change intended.
