LoongArch: Allow specify SIMD width via kernel parameters
For power saving or debugging purpose, we usually want to limit the SIMD
(LSX/LASX) usage on a rich feature platform. So allow specify SIMD width
via kernel parameters "simd=".
Allowed values of "simd=" are any integers, and recommended values are:
0: Disable all SIMD features;
128: Enable at most 128bit SIMD features;
256: Enable at most 256bit SIMD features;
-1(default): Enable as many as possible SIMD features automatically.
