Powerpc is a mess of implicit includes by prom.h. Add the necessary
explicit includes to drivers in preparation of prom.h cleanup.

The usage of strict_strtoul() is not preferred, because
strict_strtoul() is obsolete. Thus, kstrtoul() should be
used.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Just use dma_async_issue_pending() directly.

These drivers set the DMA_INTERRUPT capability bit when requesting a DMA
controller channel. This was historical, and is no longer needed.

Recent changes to the drivers/dma/fsldma.c driver have removed support
for this flag. This makes the carma drivers unable to find a DMA channel
with the required capabilities.

This adds support for programming the data processing FPGAs on the OVRO
CARMA board. These FPGAs have a special programming sequence that
requires that we program the Freescale DMA engine, which is only
available inside the kernel.
