[RFC PATCH 2/3] devicetree: provide hook to allow setting devicetree device name

[Frank Rowand <frowand.list@gmail.com>]

From: Frank Rowand <frank.rowand@sonymobile.com>

Optionally push devicetree device naming into a function called dynamically by
of_device_alloc().

TODO:
   Change made to of_device_alloc() could also be made to
   of_amba_device_create()
