f4e190e317 ARM: uniphier: enable SPL_OF_CONTROL
Device Tree really improves code maintainability and is now
available for SPL too.

This is the state-of-the-art implementation in U-boot.

The board files (platform data) are no longer needed.

28148b060d ARM: UniPhier: fix pin mux setting for USB port 2 of PH1-sLD8
The register value should be 1, not 4.

f6e7f07c17 ARM: UniPhier: replace <asm/io.h> with <linux/io.h>
In the Linux coding style, it is recommended to include <linux/io.h>
rather than <asm/io.h>.  Follow this trend.

7d1a3a67bc ARM: UniPhier: move UART pin settings to SPL
The UniPhier platform is going to enable Driver Model and UART
support on SPL.  Move UART pin settings to early_pin_init(),
which is called from SPL.

d5e7305013 ARM: UniPhier: include PH1-LD4 Makefile from PH1-sLD8
The two Makefiles arch/arm/mach-uniphier/{ph1-ld4,ph1-sld8}/Makefile
are completely the same.  We can improve the maintainability by
having one to include the other.

ea6de4ac80 ARM: UniPhier: support 1CS support card for all the UniPhier SoCs
Two support card variants are used with UniPhier reference boards:
 - 1 chip select support card (original CPLD)
 - 3 chip selects support card (ARIMA-compatible CPLD)

Currently, the former is only supported on PH1-Pro4, but it can be
expanded to PH1-LD4, PH1-sLD8 with a little code change.

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.

198a97a6ab ARM: UniPhier: split clkrst_init() into two functions
Split the current clkrst_init() into two functions:

 - early_clkrst_init(): called from SPL
  Deassert the reset signals of the memory controller and some other
  basic cores.

 - clkrst_init(): called from main U-boot
  Deassert the reset signals that are necessary for the access to
  peripherals etc.

27eac5df17 ARM: UniPhier: fix SBC init code
Now UniPhier SoCs only work with CONFIG_SPL and the function
sbc_init() is called from SPL.
The conditional #if !defined(CONFIG_SPL_BUILD) has no point
any more.

a86ac9540e ARM: UniPhier: include <mach/*.h> instead of <asm/arch/*.h>
Since commit 0e7368c6c4 (kbuild: prepare for moving headers into
mach-*/include/mach), we can replace #include <asm/arch/*.h> with
<mach/*.h> so we do not need to create the symbolic link during the
build.
