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.
