sensors: occ: Add support for OCC inband sensors
Add support to parse and export OCC inband sensors which are copied
by OCC to main memory in P9. Each OCC writes three buffers which
includes one names buffer for sensor meta data and two buffers for
sensor readings. While OCC writes to one buffer the sensor values
can be read from the other buffer. The sensors are updated every
100ms.
This patch adds power, temperature, current and voltage sensors to
/ibm,opal/sensors device-tree node which can be exported by the
ibmpowernv-hwmon driver in Linux.
