Subject: [PATCH 1/2] ARM: EXYNOS: Add aliases for i2c controller for exynos4

This is similar to a recent commit for exynos5250 titled:
  ARM: EXYNOS: Add aliases for i2c controller

Adding aliases will be useful to prevent warnings in a future
change.  See:
  i2c: s3c2410: Get the i2c bus number from alias id
