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.
Fixes: 7bfa5ab6fa1b1 ("drivers: dma-coherent: add initialization from device tree")
