Since the removal of OF_HOSTFILE logic in board_fdt_blob_setup(), the logic for obtaining the DT is handled in the OF_BOARD option. If a devicetree comes from a bloblist it is immediately overwritten by this function.
Fix this by skipping the function if a devicetree is already present.
This is sort-of a fix for e7fb7896 ("sandbox: Remove OF_HOSTFILE") but it has only come to light since bloblist was added, so I have not added a Fixes tag.
Unfortunately it is not possible to report the correct FDT source with the current code. It might be best to use an error-return code for board_fdt_blob_setup() so that an error can be reported if the board does not provide the DT.
