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 SoC is too old.  It is difficult to maintain any longer.

PH1-LD11 and PH1-LD20 have much pin controlling in common, so I
added a single driver shared between them in the initial commit.

However, the Ethernet pin-mux settings I am going to add are
different with each other, and they may diverge more as the
progress of development.  Split it into two dedicated drivers.

The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too
long.  It would not hurt to drop "PH1_" because "UNIPHIER_" already
well specifies the SoC family.  Also, rename files for consistency.

CONFIG_PINCTRL_UNIPHIER is more suitable than CONFIG_ARCH_UNIPHIER
to guard the drivers/pinctrl/uniphier directory.

The current CONFIG_PINCTRL_UNIPHIER_CORE is a bit long, so rename it
into CONFIG_PINCTRL_UNIPHIER.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one.  This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.
