isci: fix oem parameter initialization and mode detection 

1/ Since commit 858d4aa7 "isci: Move firmware loading to per PCI device" we have
   been silently falling back to built-in defaults for the parameter settings by
   skipping the call to scic_oem_parameters_set().

2/ The afe parameters from the firmware were not being honored

3/ The latest oem parameter definition flips the mode_type values which are
   now 0: for APC 1: for MPC.  For APC we need to make sure all the phys
   default to the same address otherwise strict_wide_ports will cause duplicate
   domains.

4/ Fix up the driver announcement to indicate the source of the
   parameters.

5/ Fix up the sas addresses to be unique per controller (in the fallback case)
