hwmon: (ibmpowernv) Add attributes to enable/disable sensor groups
OPAL firmware provides the facility for some groups of sensors to be enabled/disabled at runtime to give the user the option of using the system resources for collecting these sensors or not. For example, on POWER9 systems, the On Chip Controller (OCC) gathers various system and chip level sensors and maintains their values in main memory. This patch provides support for enabling/disabling the sensor groups like power, temperature, current and voltage.
