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.
