ARM: dts: exynos: Add Samsung's Exynos4412-based Midas boards

"Midas" is the codename for a family of smartphones released by Samsung
Mobile. It includes the Galaxy S3 (GT-I9300/I9305) and the Galaxy
Note 2 (GT-N7100/N7105). The boards largely have the same peripherals:
the main differences are touchscreen, display panel and cellular modem.
