checks: Remove warning for I2C_OWN_SLAVE_ADDRESS

dtc does a sanity check on reg properties that they are within the 10
bit address range for i2c slave addresses. In the case of multi-master
buses or devices that act as a slave, the binding may describe an
address that the bus will listen on as a device. Do not warn when this
flag is set.

See Documentation/devicetree/bindings/i2c/i2c.txt.

This fixes the following build warnings reported by Stephen and by Arnd:

arch/arm/boot/dts/aspeed-bmc-facebook-yosemitev2.dts:126.11-130.4:
  Warning (i2c_bus_reg): /ahb/apb/bus@1e78a000/i2c-bus@80/ipmb1@10:
    I2C bus unit address format error, expected "40000010"
arch/arm/boot/dts/aspeed-bmc-facebook-yosemitev2.dts:128.3-30:
  Warning (i2c_bus_reg): /ahb/apb/bus@1e78a000/i2c-bus@80/ipmb1@10:reg:
