This driver provides interface to mmap the OCC sensor area
to userspace to parse and read OCC inband sensors.

Why?

Is this for debug? If so, the existing exports interface should be used.

If there's actual sensors, we already have two ways of exposing sensors
to Linux: the OPAL_SENSOR API and the IMC API.

Why this method and not use the existing ones?

More than that, a sensor should be exposed to userspace via hwmon, not
some random direct userspace map.
