The new OPAL device tree for sensors has a different layout and uses new
property names, for the type and for the handler used to capture the
sensor data.
This patch modifies the ibmpowernv driver to support such a tree in a
way preserving compatibility with older OPAL firmwares.
This is achieved
Currently, sensors are only identified by their type and index.
The new OPAL device tree can expose extra properties to identify
some sensors by their name or location. This patch adds the creation
of a new hwmon *_label attribute when such properties are detected.

The kernel has orderly_poweroff which allows the kernel to initiate a

orderly_reboot that will cause userspace to shut itself down by calling
/sbin/reboot.
This will be used for shutdown initiated by a system controller on

that checks the return value.
