[PATCH v2 1/1] drm/edp-panel: Add panels used by Dell XPS 13 9345

[Aleksandrs Vinarskis]

Introduce low-res IPS and OLED panels for mentioned device.

SHP panel's timings were picked experimentally, without this patch or with
`delay_200_500_e50` panel sometimes fails to boot/stays black on startup.

LGD panel's timings were copied from other LGD panels and tested to be
working.

Particular laptop also comes in high-res IPS variant, which unfortunately
I do not have access to verify.

The raw edid for SHP panel is:
