[PATCH 1/1] PCI/VPD: Fix blocking of VPD data in lspci for QLogic 1077:2261

[Arun Easi <aeasi@marvell.com>]

"lspci -vvv" for Qlogic Fibre Channel HBA 1077:2261 displays
"Vital Product Data" as "Not readable" today and thus preventing
customers from getting relevant HBA information. Fix it by removing
the blacklist quirk.

The VPD quirk was added by [0] to avoid a system NMI; this issue has
been long fixed in the HBA firmware. In addition, PCI also has changes
to check the VPD size [1], so this quirk can be reverted now regardless
of a firmware update.

Some more details can be found in the following thread:
    "VPD blacklist of Marvell QLogic 1077/2261" [2].

  * The Amazon Annapurna Labs 0x0031 device id is reused for other non Root Port
