The current PLL code handles this wrong: instead of waiting for the bit to be cleared, it waits for the bit to be set. Usually, the bit is always set, as the CPU has just set it before. However, if the CPU takes enough time between setting the GO bit and checking it, the HW may already have cleared the bit and this leads to timeout error. Fix the wait to check the bit properly.
