[PATCH RFC 43/51] DMA-API: dma: edma.c: no need to explicitlyinitialize DMA masks

[Russell King]

register_platform_device_full() can setup the DMA mask provided the
appropriate member is set in struct platform_device_info.  So lets
make that be the case.  This avoids a direct reference to the DMA
masks by this driver.
