Looks like an unrelated change? Or is it a consequence of "not having
any in-tree users of platform_data" that plays a role here?

I probably did it because I thought I had removed the matching #ifdef
for at86rf230_of_match in the process of making the driver DT-only.

Without this trivial change, building the driver as built-in with
CONFIG_OF=n can result in a warning like

drivers/net/ieee802154/at86rf230.c:1632:28: error: unused variable 'at86rf230_of_match' [-Werror,-Wunused-variable]

It looks like this was already removed in a8b66db804f0 ("at86rf230:
remove #ifdef CONFIG_OF"), which was not technically correct, but
nobody noticed, including me.

I could split this out as a separate patch, but it's probably
not worth it.

Anyhow, the changes in the driver look good, so:
