b43: LCN-PHY: implement disabling radio

Browse Source 
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!
 read32 0xfaafc120 -> 0x04000400
 phy_read(0x044d) -> 0x0000
phy_write(0x044d) <- 0x0000
 phy_read(0x044c) -> 0x1fff
phy_write(0x044c) <- 0x1fff

 phy_read(0x04b1) -> 0x0000

phy_write(0x04fa) <- 0x0000
 phy_read(0x04f9) -> 0x007f
phy_write(0x04f9) <- 0x007f
