lib: disable non pcie types in find with resource
mpmd find doesn't respect the "resource" arg hint and can be detected
when "resource" is set. This results in incorrect device selection when
using PCIe. This change adds detection for "resource" as a prefix
in the device hints for mpmd and the other devices.
