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.

Add architecture-specific global data We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain.

global_data: Ensure we have <config.h> when symbols are not in Kconfig yet All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via <config.h>. While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any <asm/global_data.h> that uses symbols not in Kconfig does start with <config.h>. Remove this when not needed.
