019df879a9 ARM: uniphier: add ProXstream2 and PH1-LD6b support
The DDR SDRAM initialization code has not been mainlined yet, but
U-Boot proper should work.

323d1f9d5b ARM: uniphier: allow to enable multiple SoCs
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.

8469700b6c ARM: uniphier: refactor LED function
The macro, led_write(), is now only used in C sources.  There is no
more reason to keep the tricky assembly macro.  Replace it with a
new C function led_puts().

Also, rename board.h to micro-support-card.h.

0b198670c6 ARM: uniphier: remove useless wrapper functions
The wrapper functions, uniphier_board_*, are just making function
calls complex.  Remove them.

Also, use empty inline functions in case CONFIG_MICRO_SUPPORT_CARD
is disabled, so that prototype checking works.

9879842c6f ARM: uniphier: drop DCC micro support card support
Historically (for compatibility with very old platforms), two
different types of micro support cards have been used with the
UniPhier SoC development boards.  It has been painful to maintain
both.  Having one of them is enough.

105a9e705e ARM: UniPhier: remove SSC_WAY_SIZE and SSC_NUM_ENTRIES macros
Each way of the system cache has 256 entries for PH1-Pro4 and older
SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs.  The line
size is still 128 byte.  Thus, the way size is 32KB/64KB for old/new
SoCs.

To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the
constant value 32KB.  It is large enough for temporary RAM and
should work for all the SoCs of UniPhier family.

b76fa3a34b ARM: UniPhier: remove stop_mpll() from PH1-Pro4 PLL initialization
This function was intended for MN2WS0235 (what we call PH1-Pro4TV).
On that SoC, MPLL is already running on the power-on reset and it
makes sense to stop the PLL at early boot-up.
On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register,
so this function has no point.

44f597adeb ARM: UniPhier: remove EHCI platform devices
Now UniPhier platform highly depends on Device Tree configuration
(CONFIG_OF_CONTROL is select'ed by Kconfig).  Since the EHCI is only
used on main U-Boot, we can drop platform devices of the EHCI
controllers.  We still keep UART platform devices because they might
be useful for SPL.
