drm: panel-orientation-quirks: Add quirk for Lenovo Ideapad Mixx 320

The Lenovo Ideapad Mixx 320 laptop uses a portrait LCD panel, add a
quirk for this.

While at it instead of duplicating the same drm_dmi_panel_orientation_data
for 3 laptops add a generic lcd800x1280_rightside_up orientation_data and
use that for all 3 (including the new Mixx 320 entry).
