With the introduction of the supported_formats member in the
dw-hdmi-qp platform data struct, drivers that have access to this
information should now set it.

Set it in the rockchip dw_hdmi_qp glue driver.

This allows this information to be passed down to the dw-hdmi-qp core,
which sets it in the bridge it creates, and consequently will allow the
common HDMI bridge code to act on it.
