RK3288 hdmi eye-diagram test would fail when pixel clock is 148.5MHz,
and single-ended test would failed when display mode is 74.25MHz.
- Fix some code style, leave space for next patches.
- For hdmi eye-diagram test, we turn on the Transmitter Trailer-B and
  improve slopeboost to 25%-30% decrease.
- For hdmi single-ended test, we set CKLVL & TXLVL to 17 when pixel
  clock is 74.25MHz, keep CKLVL & TXLVL to 13 when pixel clock is 148.5MHz.
