drm/panel: simple: add display timings for logic technologies displays

Add display timings for the following 3 display panels manufactured by
Logic Technologies Limited:

- LT161010-2NHC e.g. as found in the Toradex Capacitive Touch Display
  7" Parallel [1]
- LT161010-2NHR e.g. as found in the Toradex Resistive Touch Display 7"
  Parallel [2]
- LT170410-2WHC e.g. as found in the Toradex Capacitive Touch Display
  10.1" LVDS [3]

Those panels may also be distributed by Endrich Bauelemente Vertriebs
GmbH [4].
