ARM: dts: keystone: i2c updates

Hi Santosh,

There are two small non critical fixes for Keystone 2 I2C DT definitions.

Changes in v2;
- added additional patch to move i2c0 device node from SoC to board files
- updated commits messages

Grygorii Strashko (2):
ARM: dts: keystone: add cell's information to i2c nodes
ARM: dts: keystone: move i2c0 device node from SoC to board files

I2C nodes should always have #address-cells and #size-cells defined,
otherwise warnings will be produced in case of adding child
nodes to the I2C bus in DT:
Warning (avoid_default_addr_size): Relying on default #address-cells value for /soc/i2c at 2530800/pca at 20 Warning (avoid_default_addr_size): Relying on default #size-cells value for /soc/i2c at 2530800/pca at 20

Hence, ensure that all i2cX nodes have #address-cells and #size-cells properties defined.

I2C devices are not the part of Keystone SoC and have to be defined in board DTS files.
Hence, move i2c0 EEPROM device node from Keystone SoC to k2hk, k2e, k2l EVM files as they all have similar EEPROM SoCs installed.

Thanks. I shall pick these up for 3.16.
