[SCSI] isci: oem parameter format v1.3 (cable select)
v1.3 allows the attenuation of the attached cables to be specified to
the driver in terms of 'short', 'medium', and 'long' (see probe_roms.h).
These settings (per phy) are retrieved from the platform oem-parameters
(BIOS rom) or via a module parameter override.

[SCSI] isci: overriding max_concurr_spinup oem parameter by max(oem, user)
Fixes bug where max_concurr_spinup oem parameter should be
overriden by max_concurr_spinup user parameter. Override should
happen only when max_concurr_spinup user parameter is specified
in command line (greater than 0). Also this fix shortens variables
representing max_conxurr_spinup for oem and user parameters.

isci: retire scic_sds_ and scic_ prefixes
The distinction between scic_sds_ scic_ and sci_ are no longer relevant
so just unify the prefixes on sci_. The distinction between isci_ and
sci_ is historically significant, and useful for comparing the old
'core' to the current Linux driver. 'sci_' represents the former core as
well as the routines that are closer to the hardware and protocol than
their 'isci_' brethren. sci == sas controller interface.
Also unwind the 'sds1' out of the parameter structs.

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)

of the parameters are in-sync.
