dmaengine: stm32-dma3: use module_platform_driver

Without module_platform_driver(), stm32-dma3 doesn't have a
module_exit procedure. Once stm32-dma3 module is inserted, it
can't be removed, marked busy.
Use module_platform_driver() instead of subsys_initcall() to register
(insmod) and unregister (rmmod) stm32-dma3 driver.
