MIPS: Detect the MSA ASE
This patch adds support for probing the MSAP bit within the Config3 register in order to detect the presence of the MSA ASE. Presence of the ASE will be indicated in /proc/cpuinfo. The value of the MSA implementation register will be displayed at boot to aid debugging and verification of a correct setup, as is done for the FPU.
