colibri-imx6ull/imx7: define bootubipart for distro boot

When using distro boot to boot from UBI volumes the boot partition
has been hardcoded to "UBI" (capital letters). However, our default
MTD layout uses "ubi" (lower case letter). Define "ubi" as the
default UBI partition for distro boot for Toradex. This allows to
use distro boot without having to redefine the MTD partition layout
which is useful for TorizonCore.
