u-boot-xlnx: Refactor SPL support

* Refactor the U-Boot SPL support to use the ps7_init_gpl.[ch] files
  from the zynq7-platform-init dependency, this allows for the files to
  come from a external source or be generated during the build
* U-Boot SPL has been split into a seperate target to allow for better
  dependency resolution as well as handling SPL building compatibility
  without generating false boot.bin files
* Clean up the u-boot-xlnx.inc file to allow for use from both the
  normal u-boot recipe as well as the u-boot-spl recipe
