Currently fallback configuration is loaded once per driver instance.
With multiple HFI devices in the same system the current code may not
load the platform config data for the device. Change fallback platform
config data loading to be per device.

Add flag in pport data structure to determine when platform config was
read from scratch registers. Change conditions in parse_platform_config
and get_platform_config_field to use the new flag.

Always initiate an offline transition request
when a link down occurs. The firmware will
use this request to confirm that the driver
has seen the link down message. A host version
is set to indicate this driver behavior to the
firmware.

Loading debug signed firmware fails if started immediately after
failed attempt to load production firmware. A short delay is
required so add about a 100us delay after RSA check failure.

Defining static data structures in a header file is wrong because
this causes the data structure to be instantiated once in every .c
file it is included in. Hence move the definition of a static
array from a header file into the only .c file in which it is used.

When reading multiple dc8051 data memory locations
at once, the read enabled field must be toggled
at every address change. Do that by writing only
the address first, then writing the enable.

Use scratch registers within the HFI1 device to recover signal
integrity information that is then used to tune the channel. While
there, update error messages to better convey the result of falling
back to a backup file.

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
