The change adds support for Sharp LQ035Q7DB03 3.5" QVGA TFT panel.
Note that this aged panel is already found in the kernel sources,
for instance in board mach files mach-mx21ads.c, mach-mx27ads.c,
mach-pcm043.c, lpd270.c and imx27-phytec-phycore-rdk.dts.

+Sharp LQ035Q7DB03 3.5" QVGA TFT LCD panel
+
+Required properties:
+- compatible: should be "sharp,lq035q7db03"
+- power-supply: phandle of the regulator that provides the supply voltage
+
+Optional properties:
+- enable-gpios: GPIO pin to enable or disable the panel
+- backlight: phandle of the backlight device attached to the panel
