Adjust the pixel mode threshold values for HDMI RX
Recently we found that the HDMI RX output becomes unstable when it
operates in dual pixel mode for the input signal with its pixel clock
slightly greater than 125MHz. The detail of the result is reported in
http://crbug.com/453416. This commit changes the pixel mode threshold
values from [115, 125] to [126, 130] to ensure that the RX operates in
single pixel mode when the pixel clock is less than 126MHz.
