drm/i915/dp: Use BDB_GENERAL_FEATURES VBT block info for builtin panel-orientation

Browse source

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.
