rocminfo is a very heavyweight mechanism for learning a lot of
information about the GPUs that are attached to the system.
It opens up the limited /dev/kfd resource to gather lots of
information about each device, while rocm_agent_enumerator really
only wants the gfx number of AMD devices attached to the system.
To avoid this heavyweight lookup in most cases, this patch switches
the order of tests. Rather than starting with rocminfo and then
falling back to a poorly-maintained PCI ID list, this patch changes
the agent enumerator to start by checking in the PCI ID list (fast
case) and then falling back to rocminfo (slow case) if the PCI ID
list is out of date.
