b43: HT-PHY: implement stopping sample tone playback
It was another sequence I recognized in HT-PHY dump: phy_read(0x00c7) -> 0x0001 phy_read(0x00c3) -> 0x0000 phy_write(0x00c3) <- 0x0002 phy_read(0x00c3) -> 0x0000 phy_write(0x00c3) <- 0x0000 The difference to N-PHY is that it writes to 6 tables instead of a one (after above).
