As you pointed of-platdata is intended for TPL/SPL to avoid the overhead 
of DTB and libraries. If this option is enabled and the driver does not 
support it, the device won't be created in TPL/SPL but is should on 
U-Boot. In order to limit the drop to SPL can CONFIG_SPL_BUILD be used?

Regarding the usefulness of im_thermal in SPL I can't comment.
