My suggestion was on same lines that if we want to use the same infra to
access information from different parts of the code then we need to
reorganize. And at same time since there is quite some data we are
planning to add in devcoredump so i recommend to have a dedicated .c/.h
instead of using amdgpu_reset.c so a clean include is easy to maintain.
Once Alex confirms it i can start working on design and what all
information we need on this.
