b43: HT-PHY: init radio when enabling it



Masks and sets were found in MMIO dumps by using MMIO hacks. Shortly:
radio_write(0x0c51) <- 0x0070
radio_write(0x0c5a) <- 0x0003
radio_write(0x0146) <- 0x0003
radio_write(0x0546) <- 0x0003
radio_write(0x0946) <- 0x0003
radio_write(0x002e) <- 0x0078
radio_write(0x00c0) <- 0x0080
radio_write(0x002e) <- 0xff87
radio_write(0x00c0) <- 0xff7f
radio_write(0x0011) <- 0xfff7
