[SPARC/64]: Prepare to remove of_platform_driver name.

The name field of of_platform_driver is just copied into the
included device_driver.  By not overriding an already initialised
device_driver name, we can convert the drivers over time to stop using
the of_platform_driver name.

Also we were not copying the owner field from of_platform_driver, so do
the same with it.
