libata: PATA-mode fixes for sis_sata

Changed PATA handler for PATA-ports used by sata_sis.
This patch was originally submitted by Jeff Garzik.

Added PCI-ID 1180 for SiS966 Controller in pata_sis.
The 1180 mode is fully compatible to other SiS PATA-controller.

The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible
to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis.
1183 is not working if simply added to pata_sis.
This handling fixes issues with SiS968.
