[PATCH 1/4] dmaengine: dw_dmac: use helper macro module_platform_driver()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

From: Heikki Krogerus <heikki.krogerus@linux.intel.com>

Since v3.2 we have nice macro to define the platform driver's init and exit
calls. This patch simplifies the dw_dmac driver by using that macro.
