dm644x_init_devices() is unnecessarily implemented as a postcore_initcall(). This does not cause any issues now, but creates issues when converting to common clock framework where clocks themselves become platform devices and are initialized later. Because of this, device clock acquisition and runtime PM on that device fails. Move the call to .init_machine() callback along with rest of platform device's registration. While at it, convert it to return void since return value is ignored by caller anyway.
