of/device: Replace struct of_device with struct platform_device

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

- * common struct device when CONFIG_OF is set to make OF-style probing
- * available to all bus types.  So now, just make of_device and
- * platform_device equivalent so that current of_platform bus users
- * can be transparently migrated over to using the platform bus.
