s5p-mfc: Add release callback for memory region devs
commit 6311f1261f59ce5e51fbe5cc3b5e7737197316ac upstream.
When s5p_mfc_remove() calls put_device() for the reserved memory region
devs, the driver core warns that the dev doesn't have a release callback:
WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90
Device 's5p-mfc-l' does not have a release() function, it is broken and must be fixed.
Also, the declared DMA memory using dma_declare_coherent_memory() isn't
relased so add a dev .release that calls dma_release_declared_memory().
Fixes: 6e83e6e25eb4 ("[media] s5p-mfc: Fix kernel warning on memory init")
