constanst to express polarity, use them to make the DTS more clear.

This patch adds support for simple GPIO-based button availabled on
Exynos4 based Odroid boards. All supported boards have POWER button,
which has been defined in exynos4412-odroid-common.dtsi. X/X2 boards
also have additional user-configurable button which has been mapped to
KEY_HOME. All defined keys have been marked as possible wakeup source.

This patch moves some parts of exynos4412-odroidx.dts to common
exynos4412-odroid-common.dtsi file and adds support for Odroid X2 and
U2/U3 boards. X2 is same as X, but it has faster SoC module (1.7GHz
instead of 1.4GHz), while U2/U3 differs from X2 by different way of
routing signals to host USB hub. It also lacks some hw modules not yet
supported by those dts files (i.e. LCD & touch panel).

To allow EXYNOS4412 based Odroidx and Origen-quad boards to operate between
200MHz to 1.4Ghz, update the vdd_arm voltage range to operate between these
cpu clock speeds.

All SoCs from Exynos4x12 series contain the MSHC block, so its node can
be located in exynos4x12.dtsi. In addition, missing clock specifiers
are added, generic SoC attributes are moved from board dts files
to common dtsi file of SoC family and the node is renamed to a more
generic name to follow node naming recommendations.

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.
