intel_infoframes didn't detect any HDMIs and looking at the source I think it
needs to be updated for Haswell.

I used the following to successfully change the infoframe to claim YCbCr 4:4:4

sudo intel_reg_write 0x60200 0x0001     ; \
sudo intel_reg_write 0x60220 0x000d0282 ; \
sudo intel_reg_write 0x60224 0x0808400f ; \
sudo intel_reg_write 0x60228 0x00000010 ; \
sudo intel_reg_write 0x6022C 0x00000000 ; \
sudo intel_reg_write 0x60200 0x1001

This changed the colors on screen, so the infoframes are clearly sent and
understood by the monitor.

I wish I had an HDMI analyzer to see what the Oppo sends.
