[PATCH 2/2] drm/panel: simple: add support for NLT NL192108AC18-02D

[Lucas Stach <l.stach@pengutronix.de>]

This adds support for the NLT Technologies NL192108AC18-02D
15.6" LVDS FullHD TFT LCD panel, which can be supported
by the simple panel driver.

Timings are taken from the preliminary datasheet, as a final
one is not yet available.
