[PATCH] dmaengine: sirf: move driver init from module_init to subsys_initcall

[Barry.Song@csr.com (Barry Song)]

From: Barry Song <Baohua.Song@csr.com>

if we initilize dma driver by module_init, there are still many devices
which will be initilized earlier than dma. these devices will fail to
get dma channel.
this moves dmaengine earlier than device_initcall and make dma available
for all devices.
