Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot
proper. Split the common code into pll-base-ld20.c for easier
re-use.

Now PLLs for DRAM controller are initialized in SPL, and the others
in U-Boot proper. Setting up all of them in a single directory will
be helpful when we want to share code between SPL and U-Boot proper.

The PLL for the DRAM interface must be initialized in SPL, but the
others can be delayed until U-Boot proper. Move them from SPL to
U-Boot proper to save the precious SPL memory footprint.

Deassert resets and enable clock signals of xHCI blocks if the
corresponding CONFIG is enabled.

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

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.

The UniPhier EHCI driver (drivers/usb/host/ehci-uniphier.c) does
nothing special but set the base address and handle reset/clock.
Since commit 4feefdcfe9 ("usb: add clock support for generic EHCI"),
the generic one (drivers/usb/host/ehci-generic.c) can do those, too.
We no longer need to stick to the dedicated driver.

These headers are only included locally in arch/arm/mach-uniphier/.
There is no reason to export them by putting in the mach/ directory.

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.
