It was just another similar-to-N-PHY and easy-to-track routine:
write32 0xb0601408 <- 0x00002057
phy_read(0x0001) -> 0x0000
phy_write(0x0001) <- 0x4000
phy_write(0x0001) <- 0x0000
write32 0xb0601408 <- 0x00002055
(b43_phy_ht_force_rf_sequence was moved up unmodified)

P.S.
There is a "msleep" usage warning, but it's in the code I just move. Will fix
sleeps/waits later globally.
