Subject: [PATCH v2 2/4] ARM: dts: exynos: Add high speed I2C ports for exynos5260

From: Stuart Menefy <stuart.menefy@...hembedded.com>

Most of the work to support the high speed I2C ports on the Exynos 5260
was added in commit 218e1496135e ("i2c: exynos5: add support for HSI2C
on Exynos5260 SoC") and the pinctrl nodes have always been available.
All that is missing to get them working is the additon of the DT bindings.

Changes since v1:
- Removed unused attribute: samsung,check-transdone-int
- Reordered additions so they now appear in address order
- Changed hex addresses to lower case
