[PATCH v2 2/2] drm/panel: Add HannStar HSD070PWW1 7.0" WXGA TFT LCD panel

[Philipp Zabel <p.zabel@pengutronix.de>]

This patch adds support for the HannStar Display Corp. HSD070PWW1 7.0"
WXGA TFT LCD panel to the simple-panel driver. The binding documentation
is included.
This panel is connected via LVDS and uses the data enable signal for
timing. Since HSYNC/VSYNC are ignored, the split between sync length and
porches is arbitrary, as long as the complete horizontal blanking interval
is 160 clocks, and the vertical blanking interval is 23 lines.

Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

Changes since v1:
 - Added bpc in panel_desc
 - Use non-zero front and back-porches
