Daniel Golle 727685c317 mac80211: rt2x00: define RF5592 in init_eeprom routine
Make sure RF5592 is set for RT5592 chip which apparently sometimes
doesn't have RF defined (but always comes with RF5592).
This patch was originally submitted on linux-wireless by
Tom Psyborg <pozega.tomislav@gmail.com> but got rejected.
Turns out the patch is actually needed.
