To get accurate and repeatable L2 cache performance metrics,
the L2 region prefetcher must be disabled. This prevents
speculative fetches from interfering with the measurements.
This patch adds a build-time option, NEOVERSE_N2_PREFETCHER_DISABLE,
to set the PF_DIS bit (bit 15) in the CPUECTLR_EL1 register for this
purpose.
