Subject: [PATCH] dw_dmac: Replace subsys_init() with arch_initcall()

In some cases users of dw_dmac, amba-pl022, are initialized before dw_dmac, and
if they try to use dw_dmac, they simply fail. So its better we register init()
routine of driver using arch_initcall() instead of subsys_init(), so that dma
driver is available at the earliest possible.
