This patch tries to integrate the existing bluestone.dts into the
apm82181.dtsi framework.
The original bluestone.dts produces a peculiar warning message.
> bluestone.dts:120.10-125.4: Warning (i2c_bus_reg):
> /plb/opb/i2c@ef600700/sttm@4C: I2C bus unit address format error, expected
> "4c"
For now, this has been kept as-is.
