[PATCH v2 5/6] arm64: dts: qcom: x1e80100: Add CCI definitions

Bryan O'Donoghue

Add in 2 CCI busses. One bus has two CCI bus master pinouts:
cci_i2c_scl0 = gpio101
cci_i2c_sda0 = gpio102
cci_i2c_scl1 = gpio103
cci_i2c_sda1 = gpio104

A second bus has a single CCI bus master pinout:
cci_i2c_scl2 = gpio105
cci_i2c_sda2 = gpio106
