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.

debug_uart_init() is called from spl_board_init(), which is only
compiled for SPL. For U-boot proper, _debug_uart_init() is unreachable,
so dropped by the dead code elimination.
Now that 64-bit SoCs of this SoC family no longer support SPL,
debug-uart-ld20.c is never compiled.

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.

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.
