core: platform: let platform_driver_probe initialize module owner

Browse Source 
Since commit 9447057eaf ("platform_device: use a macro instead of
platform_driver_register"), platform_driver_register() always overwrites
the .owner field of a platform_driver with THIS_MODULE. This breaks
platform_driver_probe() which uses it from within the platform core
instead of the module init. Fix it by using a similar #define construct
to obtain THIS_MODULE and pass it on later.
