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.
- Change files calling map_oprom_vendev()
