ARM: dts: Add minimal support for dm8168-evm
This allows booting the device with basic functionality. Note that at least on my revision c board the DDR3 does not seem to work properly and only some of the memory can be reliably used. Also, the mainline u-boot does not seem to properly initialize the ethernet, so I've been using the old TI u-boot at: http://arago-project.org/git/projects/?p=u-boot-omap3.git;a=summary Cc: Brian Hutchinson <b.hutchman@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
