Similar to Ice Lake, Intel Sapphire Rapids server also supports the
topdown performance metrics feature. The difference is that Intel
Sapphire Rapids server extends the PERF_METRICS MSR to feature TMA
method level two metrics, which will introduce 8 metrics events. Current
icl_update_topdown_event() only check 4 level one metrics events.
Factor out intel_update_topdown_event() to facilitate the code sharing
between Ice Lake and Sapphire Rapids.
