From: Clint Taylor <clinton.a.taylor@xxxxxxxxx>
HDMI audio clock config was incorrectly choosing the default for
pixel doubled interlaced modes. The table was missing pixel clock
values 13.500 (27.000) and 13.513 (27.027). Luckily the default N
value for 25.200 is the same N value for both 27MHz pixel clocks,
a warning message was being printed with drm.debug set.
ver2: Use 13500 * 1001 / 1000 instead of 13513 constant.
