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

Git-commit: 0dd5b13315fd57976f4cde050c1e763aba2ffdcf
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
