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.

As for 1920x1080 display resolution, we should turn on the Transmitter
Trailer-B, and adjust slopeboost to 25%-35% decrease.

Because of iMX6 & Rockchip have differnet mpll config parameter,
than the cklvl & txlvl would be different, we also should seperate
this parmeter.

As for Rockchip HDMI, when pixle clock less than 148MHz, the cklvl &
txlvl should be set to 13. When pixel clock less than 74.25MHz the
cklvl & txlvl should be set to 17.

* [RFC PATCH 3/3] drm: bridge/dw_hdmi: improve hdmi single-end test

Because of iMX6 & Rockchip have differnet mpll config parameter,
than the cklvl & txlvl would be different, we also should seperate
this parmeter.

As for Rockchip HDMI, when pixle clock less than 148MHz, the cklvl &
txlvl should be set to 13. When pixel clock less than 74.25MHz the
cklvl & txlvl should be set to 17.
