mvebu: cortex-a53: respect DEVICE_packages for Methode devices

Use the added support for generating per device targz rootfs so that images
generated for Methode devices when CONFIG_TARGET_MULTI_PROFILE and
CONFIG_TARGET_PER_DEVICE_ROOTFS are set, we actually get the targz rootfs
that respects DEVICE_PACKAGES.

Currently, buildbot generated images have no networking, LM75 nor I2C
working, as the generated images do not include required kmods that are
listed in DEVICE_PACKAGES.

While at it, there is no need for tar to run in verbose mode.
