ARM: dts: msm: Disable HBM mode for SW43404 panel

High brighteness mode(HBM) mode should be disabled
as default. If we let panel work on HBM mode for
long time, panel will be damaged. The highest
luminace will decrease.

To enable HBM mode for debug use below command:
echo "0x15 0x01 0x00 0x00 0x00 0x00 0x02 0x55 0x0c" > /d/dri/0/DSI-1/tx_cmd
