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()
