Subject: [PATCH] hw/ppc/e500: Add missing device tree properties to i2c
 controller node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

cheery-pick from b5d65592d931d07d4f4bcb915d018ec9598058b4

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.
