I guess drivers/mfd would be a better place than drivers/misc, but it might not
need to be an mfd driver in the sense that it registers mfd cells.

The more important point is to remove the device registration from the board
file. You definitely should not have the cells in the board file, but replacing
them with platform devices in the board file makes it no better.

My whole point has been that you register them from the main pruss driver
based on run-time data instead of compile-time pre-configured stuff in the
board file.
