This patch adds port sub-nodes to exynos4 ehci and ohci modules, which
are required by recently merged new exynos4 usb2 phy support.

This patch adds support for common hardware modules available on all
Exynos4412-based Odroid boards, which already have complete support in
mainline kernel. This includes secure firmware calls, watchdog, g2d and
fimc (mem2mem) multimedia accelerators.

Last megabyte of RAM is used by secure firmware and should not be accessed
by Linux kernel, so correct available memory size in DTS file.

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).

On Odroid U2/U3 BUCK8 is used for providing power to also to P3V3
source, which is also connected to LAN9730 chip's nRESET signal. To
reset lan chip on system reboot, the BUCK8 output should not be used in
'always on' mode. This change has no impact on X/X2 boards.

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.

TFLASH (SDHCI2 controller) uses internal card detect line, but it looks
that the driver fails to operate it properly. Use GPIO interrupt on
SD_CDn line for detecting SD card state.
