[PATCH v3 01/11] spl: Use FIT data address as fallback when 'load' property is absent

[Beleswar Padhi]

In cases where the 'load' property is not defined in a FIT image node,
fallback to using the data address returned by `fit_image_get_data()`.
This enables FIT images to omit the 'load' property during FIT creation.
