The function name indicates that it does something, but its entire
operation is actually condition on a CONFIG. Move the condition outside
the function so this is clearer, and use if() instead of #ifdef, like the
reset of the file.

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.

This can be useful to force bootcmd to execute as soon as U-Boot has
started.
My use-case is: An SoC-specific tool pushes U-Boot into RAM, along with
an image to be written to device boot flash, with the DT config property
"bootcmd" set to contain a command to write that image to flash. In this
scenario, we don't want to allow any stale bootdelay value taken from
the current flash content to affect how long it takes before the
flashing process starts.

If kernel-offset is specified in the fdt, set an environment variable
so that scripts can access the attached kernel.
This can be used by a packaging program to tell U-Boot about a kernel
that has been downloaded alongside U-Boot. The value in the fdt is
the offset of the kernel from the start of the U-Boot image, so we can
find it just by adding CONFIG_SYS_TEXT_BASE.
It is then fairly easy to put something like this in the environment
variables in the board header file:
"if test ${kernaddr} != \"\"; then "\
"echo \"Using bundled kernel\"; "\
"bootm ${kernaddr};" \
"fi; "\
/* rest of boot sequence follows here */

When secure booting is chosen:
* The u-boot shell is never invoked during boot--we just do a simple
table lookup to find the command. This means we could even remove
the shell parsing from u-boot and still be able to boot.
* The boot command can't be interruped.
* Failure doesn't cause us to fall back to the shell.
