The code in uniphier_sld3_sbc_init() is pin-muxing, so it would
be a better fit in uniphier_sld3_early_pin_init().

The System Bus is not available by default on the ROM boot mode of
PH1-LD20. To use devices connected to the System Bus, such as the
Micro Support Card, it is necessary to set up pin-muxing and some
System Bus Controller register.

There is a bunch of duplication in the System Bus Controller init
code. Roughly, there are two types in the SBC mode: Adress/Data
Multiplex Mode and Save Pins Mode. Consolidate per-SoC functions
into the two, plus per-SoC optional init code.

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.

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.

The DDR SDRAM initialization code has not been mainlined yet, but
U-Boot proper should work.

Before this commit, the Kconfig menu in mach-uniphier only allowed us
to choose one SoC to be compiled. Each SoC has its own defconfig file
for the build-test coverage. Consequently, some defconfig files are
duplicated with only the difference in CONFIG_DEFAULT_DEVICE_TREE and
CONFIG_{SOC_NAME}=y.
Now, most of board-specific parameters have been moved to device trees,
so it makes sense to include init code of multiple SoCs into a single
image as long as the SoCs have similar architecture. In fact, some
SoCs of UniPhier family are very similar:
- PH1-LD4 and PH1-sLD8
- PH1-LD6b and ProXstream2 (will be added in the upcoming commit)
This commit will be helpful to merge some defconfig files for better
maintainability.
