PATCH 1/1 sunxi: video: Add support for Hitachi tx18d42vm LVDS LCD panels

Add support for Hitachi tx18d42vm LVDS LCD panels, these panels have a lcd controller which needs to be initialized over SPI, once that is done they work like a regular LVDS panel.

PATCH 1/1 sunxi: video: Add support for Hitachi tx18d42vm LVDS LCD panels

Hi

Note this is v3, I forgot to set the subject-prefix for this. Changes since v2 are using "if (IS_ENABLED(CONFIG_...))" rather then #ifdef.

Regards,

Hans
