drm/amdgpu: refactor code to split devcoredump code

Refractor devcoredump code into new files since its
functionality is expanded further and better to slit
and devcoredump to have its own file.

v2: Fix the build failure caught by arm compiler
of implicit function declaration with #ifdef

v3: squash in fix for implicit declaration error
