[v3,05/26] hw/ppc/e500: Add missing device tree properties to i2c controller node

Commit Message

When compiling a decompiled device tree blob created with dumpdtb, dtc complains
with:

  /soc@e0000000/i2c@3000: incorrect #address-cells for I2C bus
  /soc@e0000000/i2c@3000: incorrect #size-cells for I2C bus

Fix this by adding the missing device tree properties.
