Ensure, that kernel update is performed atomically on filesystem, to
reduce likelihood of failure if power-cut occurs during sysupgrade. If
kernel update fails for whatever reason, skip updating rootfs as well.

Sysupgrade procedure for i.MX 6 Apalis boards is suitable for most other
i.MX boards booting from eMMC or SD card. Extract the common parts and
decouple the procedure from "apalis" board name in sysupgrade TAR
contents, so the procedure is reusable for i.MX 7 boards.

Modern NXP i.MX series includes several different families, based on
single- or multi-core Arm Cortex-A CPUs. To be able to support more
families within a single target, we split the 'imx' in arch-specific
subtargets, starting with 'cortexa9' for the Cortex-A9 based i.MX 6,
already supported by the original 'imx6' target.

This is first step in migrating to a generic i.MX target which in the
next steps will also get divided into arch-specific subtargets.
In the result, this will make it possible to support, within a single
target, also other modern NXP i.MX families, like the i.MX 7, i.MX 8
or recently introduced i.MX 9.
