I would use a stronger assignemnt instead of ?=
(http://www.yoctoproject.org/docs/1.6/bitbake-user-manual/bitbake-user-manual.html#setting-a-default-value)

Maybe imx-base.inc from BSP is stronger than you machine config file.

However, maybe I forgot one BSP dependency. Which package your
dependency graph say is bringing the vpu package?
