Add DT nodes for ptn3460 bridge chip and panel.
Add backlight enable pin and backlight power supply for pwm-backlight.
Also add bridge phandle needed by dp to enable display on snow.
Signed-off-by: Ajay Kumar <ajaykumar.rs@xxxxxxxxxxx>

Changes since V1:
-- Remove "simple-panel" compatible string.
-- Use GPIO_ACTIVE_HIGH instead of 0.
-- Change panel node naming from "panel-simple" to "panel".
Changes since V2:
-- Use proper compatible string: "auo,b116xw03"
