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.

sandbox: change local_irq_save() to macro local_irq_save() should be a macro, not a function because local_irq_save() saves flag to the given argument. GCC is silent about this issue, but Clang warns: In file included from lib/asm-offsets.c:15: In file included from include/common.h:20: In file included from include/linux/bitops.h:110: arch/sandbox/include/asm/bitops.h:59:17: warning: variable 'flags' is uninitialized when used here [-Wuninitialized] local_irq_save(flags); ^~~~~ That change causes another warning: In file included from include/linux/bitops.h:110:0, from include/common.h:20, from lib/asm-offsets.c:15: arch/sandbox/include/asm/bitops.h: In function ‘test_and_set_bit’: arch/sandbox/include/asm/bitops.h:56:16: warning: unused variable ‘flags’ [-Wunused-variable] So, flags should be set to __always_unused.
