The driver will now try to read directly from the EPROM as its
first choice for the platform configuration file.

Active QSFP cables were reset only every alternate iteration of the
channel tuning algorithm instead of every iteration due to incorrect
reset of the flag that controlled QSFP reset, resulting in using stale
QSFP status in the channel tuning algorithm.

QSFP CDR enablement is now controlled by determining power class
and the configuration file. We disable the DC 8051 from requesting
enablement or disabling of TX and RX CDRs by removing the code
that allowed the DC 8051 to request changes.

Two 8051 link settings, external device config and tuning method,
were written in the wrong location and the previous settings were
not cleared. For both, clear the old value and write the new
value.

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.
