Subject: [PATCH] overlay/sensors: Configure Doze brightness sensor

Oplus doze brightness sensors either reports 0 or 1

0.0 - Dark environment
1.0 - Bright environment

aod_light_mode value of 1 enables qcom,mdss-dsi-aod-low-mode-command
and any other value would enable qcom,mdss-dsi-aod-high-mode-command
