Adam Gruchala dbb0743a58 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)

README 

This defines the temporary binary blow we are to pass to the SCU
driver to emulate the binary firmware that we will eventually be
able to access via NVRAM on the SCU controller.

The current size of the binary blob is expected to be 149 bytes or larger
