Here's the pertinant question: "is it platform data?"  Looking at the
file, it appears to be internal data structures and register definitions
for the driver itself.  Therefore, it isn't platform data, and it
shouldn't be living separately from the driver.

If the driver itself only makes use of the data structures, the data
structures should be defined either within the driver, or a header file
co-located next to the driver itself.  The same goes for register
definitions too.

The only structure that I can find which isn't internal to the driver
is struct edma_soc_info, struct edma_rsv_info, and the enum dma_event_q.
Those can go to include/linux/platform_data, but the rest should not.
