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.

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"

This patchset has dependency on driver patches.
But, no harm merging it since DT bindings are almost agreed.

The below patch should be merged ASAP. Because, driver changes are already in
for this patch:
