b43: LCN-PHY: implement disabling radio

wl reads radio version, then disables it. That's how we found it in MMIO
dump:
 radio_read(0x0000) -> 0x0031 <-- RADIO READ WITHOUT 0x200 SET!
 radio_read(0x0001) -> 0x0064 <-- RADIO READ WITHOUT 0x200 SET!
 radio_read(0x0002) -> 0x0020 <-- RADIO READ WITHOUT 0x200 SET!
