[PATCH v4 32/39] ml/cnxk: enable support to get xstats in cycles

[Srikanth Yalavarthi]

Enabled support to retrieve xstats in either cycles or ns.
Access to sclk is enabled only if an RVU device is probed
during initialization. Driver would return the xstats in
nanoseconds only when an RVU device is probed, else would
fallback to cycles.
