Add initial DT for Hardkernel's ODROID-X board based on EXYNOS4412
SoC. This patch including adds the node to support fixed voltage for
peripherals like LED, ethernet controller, and this patch adds GPIO
connected LEDS on ODROID-X board and configure its properties like
following:
LED1: use 'heartbeat' trigger, blinking while the board is running.
LED2: use 'mmc0' trigger, on when mmc0 is accessing.

And adds the device node to support eMMC storage on SDCARD4 ports,
controlled by MSHC.

Commit 0cc41e4a (arch: remove direct definitions of KERN_<LEVEL>
uses) is broken - not enough thought was put into changing:

	.asciz	"string"

to

	.asciz	"string1" "string2"

The problem is that each string gets _separately_ NUL terminated, so
the result is a string containing:

	"string1\0string2\0"

rather than:

	"string1string2\0"

With our new printk levels, this ends up as - eg, KERN_DEBUG "string":

	0x01 0x00 0x07 0x00 "string" 0x00

which produces lots of \x01 in the kernel log.

The Armada XP DB evaluation board has one SD card slot, directly
connected to the SDIO IP of the SoC, so we add a device tree
description for it.

However, in the default configuration of the board, the SD card slot
is not usable: the connector plugged into CON40 must be changed
against a different one, provided with the board by the
manufacturer. Since such a manual modification of the hardware is
needed, we did not enable the SDIO interface by default, and left it
to the board user to modify the Device Tree if needed. Since this
board is really only an evaluation board for developers and not a
final product, it is not too bad.

The SDIO interface is only available on pins MPP30/31/32/33/34/35 on
the various Armada XP variants, so we provide a pin muxing option for
this in the Armada XP .dtsi files.

Even though those muxing options are the same for MV78230, MV78260 and
MV78460, we keep them in each .dtsi file, because the number of pins,
and therefore the declaration of the pinctrl node, is different for
each SoC variant.

The SDIO interface is available either on pins MPP9/11/12/13/14/15 or

are potentially possible, those two muxing options are the most
probable ones, so we provide those at the SoC level .dtsi file.

In practice, in turns out the Armada 370 DB board uses the former,
while the Armada 370 Mirabox uses the latter.
