From: Martijn Braam <martijn@xxxxxxxxx>
The phone's display is using a Hannstar LCD panel. Support it by adding a
panel DT node and all needed nodes (backlight, MIPI DSI, regulators, etc).

Changes in v3:
- Fix some ./scripts/checkpatch.pl --strict warnings.
- Add Ondrej Jirman Tested-by tag.
- Change PWM period to 50000 since 20 kHz is recommended (Ondrej Jirman).
- Remove useless comments for the panel regulators (Ondrej Jirman).
- Drop unneeded pinctrl pull down conf for pins that either already have
a pull-down resistor or are already driven by the SoC (Ondrej Jirman).
- Remove "pwm-delay-us" property not supported in mainline (Ondrej Jirman).
Changes in v2:
- Drop touchscreen node because used the wrong compatible (Ondrej Jirman).
- Fix assigned-clock-parents in vopb node (Ondrej Jirman).
- Add vopl and vopl nodes.
