[PATCH v2] PCI/VPD: Remove not any longer needed Broadcom NIC quirk

[Heiner Kallweit <hkallweit1@gmail.com>]

This quirk was added in 2008 [0] when we didn't have the logic yet to
determine VPD size based on checking for the VPD end tag. Now that we
have this logic [1] and don't read beyond the end tag this quirk can
be removed.

[0] 99cb233d60cb ("PCI: Limit VPD read/write lengths for Broadcom 5706, 5708, 5709 rev.")
[1] 104daa71b396 ("PCI: Determine actual VPD size on first access")

This is basically the same as what you're currently discussing
for the Marvell / QLogic 1077 quirk.
