Respect SOURCE_DATE_EPOCH when building FIT images.
Embedding timestamps in FIT images results in unreproducible builds
for targets that generate a fit image, such as dra7xx_evm.
This patch uses the SOURCE_DATE_EPOCH environment variable, when set,
to use specified value for the date.
Thanks to HW42 for debugging the issue and providing the patch:
