mac80211: move OF stuff to ath9k_of_init

It's the proper function to handle this stuff in.

The original patch abused the fact that the ath9k driver in init called
ath9k_init_platform to populate all the needed configuration. This is
the wrong place to do so and it also goes away in 6.13.

Move 553-ath9k_of_gpio_mask.patch contents to ath9k_of_init where they
belong.
