drm: rockchip/dw_hdmi-rockchip: improve for HDMI electrical test
When pixel clock less than 148.5MHz, make sloopboost=2 tklvl=20
cklvl=13 increase rasing/falling time and increase data & clock
voltage driver.
When pixel clock less than 74.25MHz, make sloopboost=0 tklvl=19
cklvl=18, increase data and clock voltage driver.
