[PATCH] base: dma-coherent: fix device_init initialization

[Felipe Balbi]

commit 7bfa5ab (drivers: dma-coherent: add initialization
from device tree) added support for dma coherent pool for
DeviceTree. Unfortunately that commit introduced a new
build warning because of a wrong type on the definition
of ->device_init(). This patch fixes it.
