d39c3ed626 soc/cores/led: Review/Rework #1265. 
- Split FSM in Main FSM/Xfer FSM to decouple Led data read from bit xfer and do read during xfer.
- Only keep optimization that are easily to understand.
- Default to new WS2812 revision (Since also works on old revision).
- Test 75/50/25MHz sys_clk_freq.
