Add MMI & MSA runtime detection for MIPS. Basically there are two code pathes. For systems that natively support CPUCFG instruction or kernel emulated that instruction, we'll sense this feature from HWCAP and report the flags according to values grab from CPUCFG. For systems that have no CPUCFG (or not export it in HWCAP), we'll parse /proc/cpuinfo instead.
