Subject: [PATCH v3 19/22] hwmon: (core) Add hwmon_max to hwmon_sensor_types enumeration

It's useful to know the maximum types of sensor supported by hwmon
framework. It can be used to allocate some data structures when sorting
the monitors based on their type.

This will be used by scmi hwmon support.
