u-boot inc: update inc file for newer u-boot versions

* Add support for different suffixes found with later u-boot
  versions which have switched from .bin to .img
* Allow recipes that include u-boot.inc to also package an
  SPL if they build one.
    * Minimum requirement is to set the SPL_BINARY value to add
      the SPL to the u-boot package as well as into the deploy
      directory.
