connector_info: Fix HDMI/DVI default bytes per color setting

According to the Programming Reference Manual and more specificaly
`TRANS_DDI_FUNC_CTL' register description, a bytes per colors value of
6 (or 10) is not supported by HDMI.

We indeed noticed that if we use a HDMI monitor on the first HDMI port
of a board without eDP, the monitor does not accept the configuration.

This patch ensures that we do not use a default BPC of 6 if the port
is HDMI.
