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 converts the following to Kconfig:
CONFIG_CONS_INDEX
We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in
drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

-e '/CONFIG_SYS_NO_FLASH=y/d' \
-e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

Currently, CMD_PXE is forcibly enabled in config_distro_defaults.h, so
that general purpose distributions can rely on it being defined. This
header is included, under conditions or not, by various archs or
famillies of archs / SoCs.
However, it is very possible that boards based on those SoCs will not
have a physical ethernet connector at all, even if the have a MAC; for
example, the Nanopi Neo AIR (sunxi H3) does not. It is also possible
that network booting is absolutely not necessary for a device.
However, it is not possible to disable the PXE command, as it is
forcibly enabled and is non-configurable.
But it turns out we already have a config option to build a distro-ready
image, in the name of DISTRO_DEFAULTS.
Move CMD_PXE out of the hard-coded config_distro_defaults.h into a
Kconfig option, that gets selected by DISTRO_DEFAULTS when it is set.
