Tests the following for both P9 and P10:
  - I2C master POR status
  - I2C master status after immediate reset
Tests the following for powernv10-ranier only:
  - Config pca9552 hotplug device pins as inputs then
    Read the INPUT0/1 registers to verify all pins are high
  - Connected GPIO pin tests of P10 PCA9552 device.  Tests
    output of pins 0-4 affect input of pins 5-9 respectively.
  - PCA9554 GPIO pins test.  Tests input and ouput functionality.
