On MTL ChromeOS boards, during AI based video conference, we were observing a lot of overhead from invalidations. Upon debug, it was found that we were using clflush in this function and that isn't efficient. With this change, while executing compute workloads like zoo models, we are getting ~25% performance improvements in a best case scenario. Rework: * Jordan: Call intel_clflushopt_range() rather than __builtin_ia32_clflushopt() because intel_mem.c is not compiled with -mclflushopt.
