[PATCH 1/2] boot: Fix dtbo application by ensuring overlay alignment

[Jamie Gibbons]

After U-Boot's DTC/libfdt update, device tree overlay application could
fail with FDT_ERR_ALIGNMENT due to the overlay DTBO being loaded at a
misaligned address. Change the FIT image loader option in image-fit.c
from FIT_LOAD_IGNORED to FIT_LOAD_OPTIONAL_NON_ZERO, to ensure overlays
are loaded at properly aligned addresses and any alignment errors are
resolved.

Tested on: PolarFire SoC Icicle Kit

Fixes: 0535e46d55d ("scripts/dtc: Update to upstream version v1.7.2-35-g52f07dcca47c")
