[PATCH 08/12] of/platform: provide a separate routine for device initialization

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

The early platform device framework will need to initialize the
platform device objects without them being allocated in
of_device_alloc(). Provide a routine that allows it.
