drm/edp-panel: Add touchscreen panel used by Lenovo X13s 



After (checks watch) a little over two years I finally investigated the
boot warning on my Thinkpad X13s and it was caused by the conservative
timings warning in panel-edp.c . The X13s was sold with a variety of
different panel versions; I have the 300 nit multi-touch variant.

I have been unable to secure panel documentation so the I copied the
timings from NV133WUM-N63.

The raw EDID is:

00 ff ff ff ff ff ff 00 09 e5 84 0a 00 00 00 00
