[PATCH 5/6] i2c: ibm_iic: use devm_ functions

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
