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].

Changes in v4:
- Added recently made mandatory connector_type information as pointed
  out by Sam.

Changes in v3:
- Fix typo in pixelclock frequency for lt170410_2whc as recently
  discovered by Philippe.

Changes in v2:
- Added Philippe's reviewed-by.
