SPDX: Convert all of our single license tags to Linux Kernel style

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.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

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.

arm: socfpga: Restructure FPGA driver in the preparation to support A10

Move FPGA driver which is Gen5 specific code into Gen5 driver file
and keeping common FPGA driver intact. All the changes are still keeping
in driver/fpga/ and no functional change. Subsequent patch would move
FPGA manager driver from arch/arm into driver/fpga/.

Revert "arm: socfpga: set the fpga global bit to disable HPS to FPGA signals"

Apparently, the logic for the FPGA global bit is not universal between Gen5
and Gen10 devices is not the same. Disabling this bit, while applicable to
Gen10 devices, will break FPGA programming on Gen5 devices.
