[PATCH v3 4/4] of/platform: Use platform_device interface

[Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com>]

of_platform_device_create_pdata() was using of_device_add() to create
the devices, but of_platform_device_destroy was using
of_platform_device_destroy().

of_device_add(), do not call insert_resource(), which initializes the
parent field of the resource structure, needed by release_resource(),
called by of_platform_device_destroy().

This leads to a NULL pointer deference.

This patch, replaces of_device_add() with platform_device_data().
