Subject[PATCH 01/11] mv64x60_wdt: set up platform_device in platform code
The driver previously registered its platform device data in its own
init function--that's bogus. Move that code to platform-specific
code in arch/ppc. This is being done so that the platform code can
decide at runtime whether to initialize this driver or not.
