drm/i915: parse child device from VBT
On some laptops there is no HDMI/DP. But the xrandr still reports
several disconnected HDMI/display ports. In such case the user will be
confused.
>DVI1 disconnected (normal left inverted right x axis y axis)
>DP1 disconnected (normal left inverted right x axis y axis)
>DVI2 disconnected (normal left inverted right x axis y axis)
>DP2 disconnected (normal left inverted right x axis y axis)
>DP3 disconnected (normal left inverted right x axis y axis)
This patch set is to use the child device parsed in VBT to decide whether
the HDMI/DP/LVDS/TV should be initialized.
Parse the child device from VBT.
The device class type is also added for LFP, TV, HDMI, DP output.
