8de303bae4 hwmon: (ibmpowernv) Use platform 'id_table' to probe the device
The current driver probe() function assumes the sensor device to be
always present and gets executed every time if the driver is loaded,
but the appropriate hardware could not be present.

So, move the platform device creation as part of platform init code
and use the 'id_table' to check if the device is present or not.

bb4398e1de powerpc/powernv: Fix endian issues with OPAL async code
OPAL defines opal_msg as a big endian struct so we have to
byte swap it on little endian builds.

7224adbbb8 powerpc/powernv: Enable fetching of platform sensor data
This patch enables fetching of various platform sensor data through
OPAL and expects a sensor handle from the driver to pass to OPAL.
