fpga: Define bitstream type based on command selection
Clean up partial, full and compressed bitstream handling. U-Boot supports full bitstream loading and partial based on detection which is not 100% correct. Extending fpga_load/fpga_loadbitstream() with one more argument which stores bitstream type. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
