[PATCH 4/5] cxgb3: Use VPD API in t3_seeprom_wp()

[Heiner Kallweit <hkallweit1@gmail.com>]

Use standard VPD API to replace t3_seeprom_write(), this prepares for
removing this function. Chelsio T3 maps the EEPROM write protect flag
to an arbitrary place in VPD address space, therefore we have to use
pci_write_vpd_any().
