Generate *.spi.img files for SPI loading on AM335x.

Please ignore the first patch. That was a bad approach.

I have two questions.
1. Does the af inventions GF board support SPI boot? If not, we can drop the
   spi image generation.
2. Building the barebox with more than one core will produce errors:

fopen: No such file or directory
  SPI-IMG images/start_am33xx_phytec_phycore_sram_128mb.pblx.mlospi
  SPI-IMG images/start_am33xx_phytec_phycore_sram_512mb.pblx.mlospi

make[1]: *** [images/start_am33xx_phytec_phycore_sram_2x512mb.pblx.mlospi] Fehler 1
make: *** [images] Fehler 2

This seems to be a makefile dependency problem. Any ideas how to fix this?
