configs: Add simple check for valid GPU MMIO trace
This file is a required input to the simulator for GPUFS. There seems to
be confusion from several users who are not providing this input. This
usually results in the amdgpu driver failing to load, leading to the
application under test exiting along with it.
This changeset adds a simple md5 hashsum check to compare against the
known good MMIO trace located in the gem5-resources repository.
