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.

ARM: uniphier: support Debug UART For ARM32 architecture, CONFIG_DEBUG_LL is available for early low-level debugging (and actually UniPhier 32bit SoCs use it), but ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART is available as an architecture-independent debug facility. This commit supports it on all the UniPhier SoCs (including the new ARMv8 SoCs), which is very useful for new SoC bringups.

ARM: uniphier: move sg_set_{pinsel, iectrl} to more relevant places Move the sg_set_pinsel macro to arch/arm/mach-uniphier/arm32/debug_ll.S since it is not used anywhere else. Move the C functions sg_set_{pinsel,iectrl} to debug-uart.c since they are not used anywhere else.
