ppc/pnv: Test pnv i2c master and connected devices

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
