Subject: [PATCH] drm/panel-simple: Add Vivax TPC-9150 panel

The model and make of the LCD panel of the Vivax TPC-9150 is unknown,
hence the panel settings that were retrieved with a FEX dump are named
after the device NOT the actual panel.

The LCD in question is a 50 pin MISO TFT LCD panel of the resolution
1024x600 used by the aforementioned device.
