Following patch reprograms SIL3114 into PCI IDE native mode compatible class code allowing
legacy software to recognize it as IDE and boot from it. I think
this should be the default for two Tyan boards (k8s aka s2882 and s2881).
Rename the directory to sil prefix to match the Linux kernel naming.
(And I think it was a SiliconSystems wish to be named sil ;)
