Yes, this is true for quite some drivers I am moving around. I think
there are two reasons: a) the board code never made it upstream
b) DT conversion happened and platform_data is now cruft. As mentioned
in the cover-letter, I didn't dive deeper for all the drivers.

I'd prefer to keep them. If they are needed again, DT conversion is
likely and easier than restarting from scratch. Guenter Roeck also
prefers to not unnecessarily annoy people who might have out-of-tree
board code. So, as long as they are not painful, let's keep them?
