NVIDIA's Tegra114 has 5 i2c controllers. These controllers have
following changes which makes incompatible with previous hardware:
- Single clock source to i2c controller.
- Interrupt support for per packet transfer.
Add DT entry for i2c controllers and make it compatible with
"nvidia,tegra114-i2c".

Changes from V1:
- None
Changes from V2:
- Rebase to for-3.10/dt of Stephen's tegra tree.
- Better describe why Tegra114 is not compatible with previous hardware.
