This patch adds syscon based phandle to i2c device nodes of exynos5250
and exynos5420. These phandles will be used to save restore i2c sysreg
configuration register during s2r from i2c driver.

Applied with change the subject 'ARM: dts: add sysreg phandle to...'

BTW I'm holding on 2nd because conflicts between pm update and cleanup
branches in my tree...
