Subject: [PATCH 07/10] arm: dts: owl-s500: Add I2C nodes

Add I2C controller nodes for Actions Semi S500 SoC.

Note the Actions Semi Owl SoC's I2C driver seems to be fully compatible
with the Actions Semi S500 SoC, even though this is not explicitly
mentioned in the source code. Hence, for the moment, enable the I2C
controller node via the "actions,s900-i2c" compatible string.
