Add support for loading FPGA into the SPL fitImage support. The
mechanism is flexible and allows user to override the actual
function for loading the FPGA itself. This is because on some
systems, the FPGA must be programmed to allow DRAM access, so
loading the full fitImage may not be possible if it contains
the bitstream. Instead, the spl_load_fpga_image() provides all
the tools to load the bitstream in parts while programming it
into the FPGA.

For sama5d2_xplained_spiflash_defconfig, we have the demo layout
as presented on this link:
http://www.at91.com/linux4sam/bin/view/Linux4SAM/Sama5d2XplainedMainPage#SPI_eMMC_Flash_demo_Memory_map



on SPI Flash (4 Mbyte) we have Bootstrap (second level bootloader), U-boot + env

and kernel+dtb we keep on eMMC on single partition in /boot directory, formatted
with ext4.

Thus, changing the boot command to reflect this demo for the spiflash config,
and fixing up bootargs. Sama5d2_xplained does not have NAND flash, so the
bootargs were completely wrong.

Tested on SAMA5D2_Xplained board (sama5d2_xplained_mmc_defconfig)

Looks like crash is introduced by commit:
"fa9ca8a5" fs/ext4/ext4fs.c: Free dirnode in error path of ext4fs_ls

Issue is that dirnode is not initialized, and then freed if the call
to ext4_ls fails. ext4_ls will not change the value of dirnode in this case
thus we have a crash with data abort.

I added initialization and a check for dirname being NULL.
