drivers: of: add return value to of_reserved_mem_device_init()
Driver calling of_reserved_mem_device_init() might be interested if the initialization has been successful or not, so add support for returning error code. This fixes a build warining caused by commit 7bfa5ab6fa1b ("drivers: dma-coherent: add initialization from device tree"), which has been merged without this change and without fixing function return value.
