Some devices with a builtin panel have the panel mounted upside down,
this is indicated by the rotate_180 bit in the BDB_GENERAL_FEATURES VBT
block.
We store this info in dev_priv->vbt.orientation, use this to set the
connector's orientation property so that fbcon and userspace will show
the image the right way up on devices with an upside-down mounted panel.
This fixes the image being upside-down on a Teclast X89 tablet.
