Initial device trees for UniPhier SoCs: PH1-sLD3, PH1-LD4, PH1-Pro4,
and PH1-sLD8.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
---

Changes in v3:
  - License under GPL/X11
  - Drop "earlyprintk" kernel-parameter, add "stdout-path" property
  - Add syscon device for SMP boot support in order not to
    hard-code register address in platsmp.c

Changes in v2: None

Using syscon here is a good idea, but please name the register area
according to what it is called in the data sheet, not according to how
it is used in Linux, and list all the registers that belong in this
device. It's quite possible that another driver needs a second
register from the same syscon.

E.g. if there is a device called a foo controller, make this device

	foo-controller@0x59800000 {
		compatible = "socionext,uniphier-foo-controller", "syscon";
		reg = <0x59800000 0x4000>;
	};

then hardcode the 0x1208 offset in the smp code, or add it as an
argument to the property containing the phandle.

OK, I updated this part in v4.
