gma hsw+: Add default value for HDMI buffer levels

Add a configuration option to override the default HDMI translation.
It's not exported yet, as we've never seen a non-default value being
used. So this is just to have a common place for the defaults.

Also sets the recommended default value for Broxton as defined in the
PRM.
