zephyr: herobrine: Update I2C bus labels
The EC chip provides a default label for every I2C bus. Override the
default label with a label matching the schematic net name.
Typing "i2c scan <tab>" on Herobrine now shows the following labels:
uart:~$ i2c scan
I2C_SENSOR I2C_EEPROM I2C_RTC I2C_USB_C1_PD I2C_USB_C0_PD
I2C_POWER
BUG=none
BRANCH=none
TEST=Boot Zephyr on herobrine, verify the new I2C bus labels
