PATCH 1/1 ata_piix: Add device ID for ICH4-L

ICH4-L is a variant of ICH4 lacking USB2 functionality and with some different device IDs.

It is documented in Intel specification update 290745-025, currently at <http://www.intel.com/assets/pdf/specupdate/290745.pdf>, and is included in the device ID table for piix.

This is untested; I don't have this device but just compared the device ID tables.

Ben.
