Precedence: bulk

Add nodes for the two CCI blocks found on SM6350.

The first contains two i2c busses and while the second one might also
contains two busses, the downstream kernel only has one configured, and
some boards use the GPIOs for the potential cci1_i2c1 one other
purposes, so leave that one unconfigured.
