The KERNCZ is new AMD SB/FCH generation name, like HUDSON2 is old FCH
generation.
We will adopt 0x790b as device ID since from this KERNCZ gereration.

The i2cpiix4.c driver and eMMC driver both will use this device ID
macro, Do you think I should submit two patches synchronously? like
patch1: change i2cpiix4 driver to use PCI_DEVICE_ID_AMD_KERNCZ_SMBUS,
patch2: for eMMC quirk in sdhci-pci.c?

And then the PCI_DEVICE_ID_AMD_KERNCZ_SMBUS can be go into pci ids.h?
