[PATCH 3.16 008/346] PCI: Mark Atheros AR9485 and QCA9882 to avoid bus reset

[Ben Hutchings]

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Blake <chrisrblake93@xxxxxxxxx>

commit 9ac0108c2bac3f1d0255f64fb89fc27e71131b24 upstream.

Similar to the AR93xx series, the AR94xx and the Qualcomm QCA988x also have
the same quirk for the Bus Reset.
