Changeset 40948 restored an older (and uglier!) version of the
code for reading the athxk calibration partition on lantiq
xway boards. As a result pci fixups stored in this partition
are no longer applied, breaking wireless on the BTHOMEHUBV2B
and (I imagine) on the DGN3500. This is a minimal patch to
restore this functionality for ath9k without reverting any
of the other changes in changeset 40948.
Note for John Crispin:
I guess you won't want to apply this patch if you are planning
to check changeset 40948 anyway yourself. I produced it for
my own use and thought I might as well send it in in case it
was any use to anyone.
