drm/panel-edp: Add BOE NE14QDM panel for Dell Latitude 7455

Cannot confirm which variant exactly it is, as the EDID alphanumeric data
contains '0RGNR' <0x80> 'NE14QDM' and ends there; but it's 60 Hz and with
touch.

I do not have access to datasheets for these panels, so the timing is
a guess that was tested to work fine on this laptop.
