of: kill struct of_device
Now that the device tree node pointer has been moved out of struct
of_device and into the common struct device, there isn't anything
unique about of_device anymore. In fact, there isn't much need
for a separate of_bus when all busses have access to OF style
probing.
arch/powerpc and arch/microblaze are moving away from using the of_bus
and using the regular platform bus instead for mmio devices. This
patch makes of_device the same as platform_device as a stepping stone
in migrating of_platform_drivers over to the platform bus.
