mb/siemens/mc_ehl2: Disable L1 prefetcher
As for mainboard mc_ehl1, a hard real-time dependency is also required
for this mainboard. The L1 prefetcher on Elkhart Lake is too aggressive
which in the end leads to an increased number of cache misses. Disabling
the L1 prefetcher boosts up the performance (in some cases by more than
10 %) in this specific use case.
