FP4: Switch to dot product CPU variant

 * FP4:/ $ cat /proc/cpuinfo | grep -m 1 Features
   Features: fp asimd evtstrm aes pmull sha1 sha2 crc32
   atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp

 * From this, it's evident that our CPU (Snapdragon 680)
   supports all the features of ARMv8.2-DotProd [1].
   Moreover AOSP sets this arch variant in their generic
   cortex-a55 ART target as well [2]. This should unlock
   some optimizations in different code paths.
