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)
