[PATCH 2/2] ARM: dts: Add DT changes for display on peach_pit

Add DT nodes for ps8622 bridge chip and panel.
Add backlight power supply for pwm-backlight.
Also add bridge phandle needed by dp to enable display on peach_pit.

Note that, peach_pit doesn't support "chunghwa,claa101wb01" panel,
but still we choose to reuse the binding since "chunghwa,claa101wb01"
has similar LCD timings.

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