There shouldn't be a need to call private spl_load_fpga_image()
because the whole sequence should be already handled by fpga_load().
The patch let spl_load_fit_image() to load data to right location based
on "load" property in FIT and then call fpga_load().
The patch is partially reverting
"spl: fit: Add support for loading FPGA bitstream"
