[PATCH 2/2] drm/panel: simple: Add Jiangsu Smartwin SMMT043480272A-A19 panel

[Marco Felsch <m.felsch@pengutronix.de>]

From: Rouven Czerwinski <r.czerwinski@pengutronix.de>

Add support for the Jiangsu Smartwin SMMT043480272A-A19 4.3" 480x272
TFT-LCD panel. The timings are based on the ILI6485 controller IC
datasheet.
