    Reverse Vendor ID & Device ID for map_oprom_vendev()
    
    - When calling map_oprom_vendev() the vendor ID and device ID
      are joined into a 32 bit value.  They were reversed from the
      order that I would have expected - Device ID as the high 16 bits
      and the Vendor ID as the low 16.  This patch reverses them so
      so that the the dword comparison in map_oprom_vendev() matches
      what's entered into Kconfig for vendor,device.
