Commit a5b6b67364cb ("arm64: tegra: Add ID EEPROM for Jetson TX1 module") populated the EEPROM on the Jetson TX1 module, but did not enable the corresponding I2C controller. Enable the I2C controller so that this EEPROM can be accessed.

The following warning is observed on the Jetson TX2 platform ...
WARNING KERN tegra-sor 15540000.sor: 15540000.sor supply \ vdd-hdmi-dp-pll not found, using dummy regulator
The problem is caused because the regulator for the SOR device is missing the '-supply' suffix in Device-Tree. Therefore, add the '-supply' suffix to fix this warning.
