Since kho_add_subtree() now accepts arbitrary data blobs (not just FDTs), rename the parameter from 'fdt' to 'blob' to better reflect its purpose. Apply the same rename to kho_remove_subtree() for consistency. Also rename kho_debugfs_fdt_add() and kho_debugfs_fdt_remove() to kho_debugfs_blob_add() and kho_debugfs_blob_remove() respectively, with the same parameter rename from 'fdt' to 'blob'.
