X-Git-Tag: v2018.07-rc1~133^2~37

board: ge: bx50v3: detect the monitor type by reading VPD earlier

Move the VPD reading earlier in order to establish the monitor
type as soon as possible.

The configuration of the specific environment variables needs to be
done later after the environment is configured.
