Specify a channel zero in idle state to avoid enterring tri-stated state
for PCA9547.

Some information about E-00013:
- Description: I2C1 and I2C3 buses are missing pull-up.
- Impact: When the PCA954x device is tri-stated, the I2C bus will float.
  This makes the I2C bus and its associated downstream devices
  inaccessible.
- Hardware fix: Populate resistors R189 and R190 for I2C1 and resistors
  R228 and R229 for I2C3.
- Software fix: Remove the tri-state option from the PCA954x
  driver(PCA954x always on enable status, specify a channel zero in dts to
  fix the errata E-00013).
