From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
Previously the variant resource structs, ops, etc., were in no obvious
order (mostly but not consistently in *Synopsys* IP rev order, which is not
reflected in the naming).
Reorder them in order of the struct and function names. No functional
change intended.
