drm/panel: simple: add Tianma P0700WXF1MBAA panel
Add the Tianma P0700WXF1MBAA 7" 1280x800 LVDS RGB TFT LCD panel.
Reuse the timings of the TM070JDHG34-00 as they are identical, even though
they are described differently by the datasheet as noted in the
comment. Power up/down timing are slightly different, so add a new struct
panel_desc for that.
