Add support for loading FPGA bitstream to get DDR up running before
U-Boot is loaded into DDR. Boot device initialization, generic firmware
loader and SPL FAT support are required for this whole mechanism to work.

Add FPGA driver to support program FPGA with FPGA bitstream loading from
filesystem. The driver are designed based on generic firmware loader
framework. The driver can handle FPGA program operation from loading FPGA
bitstream in flash to memory and then to program FPGA.

Current watchdog reset is misplaced after for-loop status polling, so
this poses a risk that watchdog can't be reset timely if polling taking
longer than watchdog timeout. This patch moving the watchdog reset
into polling to ensure the watchdog can be reset timely.

The 'status' variable in 'socfpga_load()' for both gen5 and arria10
is of type 'unsigned long' while it is always used as 'int' only.
Change it to 'int'.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.
