[FFmpeg-devel] [PATCH 2/2] lavu/riscv: add hwprobe() for CPU detection

This adds the Linux-specific function call to detect CPU features. Unlike the more portable auxillary vector, this supports extensions other than single lettered ones. At this point, FFmpeg already needs this to detect Zba and Zbb at run-time, and probably will need it for Zvbb in the near future.
