Previously, during the rsmi_init discovery process, the existence of an hwmon# directory was used to distinguish between gpus nodes and non-gpu nodes. This isn't reliable in some scenarios. Instead, the existence of the vbios_version file is used as an indicator that the node is indeed a gpu. Change-Id: Icfbe5c42ed0970077b05f25c3d209308a31bec85
