[PATCH] vr41xx: convert to the new platform device interface

The patch does the following for v441xx seris drivers:

 - stop using platform_device_register_simple() as it is going away
 - mark ->probe() and ->remove() methods as __devinit and __devexit
   respectively
 - initialize "owner" field in driver structure so there is a link
   from /sys/modules to the driver
 - mark *_init() and *_exit() functions as __init and __exit
