isci: Added support for C0 to SCU Driver
C0 silicon updates the pci revision id and requires new AFE parameters for phy signal integrity. Support for previous silicon revisions is deprecated (it's also broken for the theoretical case of multiple controllers at different silicon revisions, all the more reason to get it removed as soon as possible) Signed-off-by: Adam Gruchala <adam.gruchala@intel.com> [fixed up deprecated silicon support] Signed-off-by: Dan Williams <dan.j.williams@intel.com>
