mac80211: rt2x00: define RF5592 in init_eeprom routine

Browse Source 
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.
