arago.conf: Set preferred kernel version for am335x
arago.conf: Set preferred kernel version for am335x

* For now linux-am335x_3.2.0-psp04.06.00.08 is not the default kernel for
  am335x. Therefore, a PREFERRED_PROVIDER and PREFERRED_VERSION needs to
  be set to make sure the Arago SDK picks up the right kernel.
