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: use pr_() instead of printf() where appropriate

Replace printf() with pr_() to specify proper loglevel.

ARM: uniphier: replace <linux/err.h> with <linux/errno.h>

These files only need error number macros. Actually, IS_ERR(),
PTR_ERR(), ERR_PTR(), etc. are not useful for U-Boot. Avoid
unnecessary header includes.

ARM: uniphier: rework existing DDR PHY code to reuse for LD11 SoC

The DDR PHY register view of LD11 is slightly different from that
of LD4/Pro4/sLD8, but it will be possible to share the register
macros (and I want to re-use as much code as possible). Change
the code in the more flexible form.

ARM: uniphier: rename function names ph1_* to uniphier_*

Eliminate the "ph1"_ prefixes from function names because "uniphier_"
describes the SoC familiy better.

ARM: uniphier: drop PH1- prefix from CONFIG options and file names

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.
