Lars-Peter Clausen 27b786e92f imageon_loopback: Use BUFIO for the HDMI clock buffer
Since we are just doing a loopback all the logic is contained within the
IO bank. By using a BUFIO instead of a BUFG we avoid having to route the
clock signal from the IO bank to the middle of the FPGA and back to the IO
bank. This reduces the skew between clock and the data signals and makes
sure that the we can use the same design over a range of different
resolutions without having to calibrate the delay.

Lars-Peter Clausen 02b5ce82ad imageon_loopback: Invert transmit clock
The ADV7511 samples on the rising edge. Update the data on the falling
edge, this gives us a larger margin and improved signal stability.
