image: Add boot_get_fpga() to load fpga with bootm
Add function boot_get_fpga() which find and load bitstream to programmable logic if fpga entry is present. Function is supported on Xilinx devices for full and partial bitstreams in BIN and BIT format. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Remove additional blankline in image.h
