b43: HT-PHY: calibrate radio after switching channel
After uploading radio values calibration goes in. In MMIO dump it is: radio_read(0x002b) -> 0x0008 radio_write(0x002b) <- 0x0008 radio_read(0x002e) -> 0x0004 radio_write(0x002e) <- 0x0000 radio_read(0x002e) -> 0x0000 radio_write(0x002e) <- 0x0004 radio_read(0x002b) -> 0x0008 radio_write(0x002b) <- 0x0009 To find masks and sets, MMIO hacks were used to fool closed driver.
