[PATCH 2.6.27-rc4][RESEND] i2c-i801: SMBus patch for Intel Ibex Peak DeviceIDs

[Seth Heasley]

This patch adds the Intel Ibex Peak (PCH) SMBus Controller DeviceIDs.

Changes are reflected in i2c-i801.c in response to updates to pci_ids.h.  The SMBus Controller is now referred to as PCI_DEVICE_ID_INTEL_PCH_SMBUS, a change to the old naming convention of PCI_DEVICE_ID_INTEL_PCH_x.
