[PATCH v2 06/10] automation: qemu-smoke-arm32.sh: Modify script to use ImageBuilder

[Michal Orzel <michal.orzel@xxxxxxx>]

Take an example from arm64 qemu test scripts and use ImageBuilder
to generate u-boot script automatically. Calculating the addresses
manually is quite error prone and also we will be able to benefit
from using ImageBuilder when adding domUs to this test in the future.

Install and use u-boot from the debian package.
Modify the script so that binaries are loaded from u-boot via tftp.
Remove dtuart=/pl011@9000000 because stdout-path in QEMU dtb is always
set to pl011 node path.

Signed-off-by: Michal Orzel <michal.orzel@xxxxxxx>

Changes in v2:
- add explanation in commit msg why we remove dtuart path
