Add DT nodes for panel-simple "auo,b133htn01" panel.
Add backlight enable pin and backlight power supply for pwm-backlight.
Also, add panel phandle needed by dp to enable display on peach_pi.
Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com>
---
Changes since V1:
Remove "simple-panel" compatible string and use only ""auo,b133htn01".
Changes since V2:
As suggested by Andreas,
Use GPIO_ACTIVE_HIGH for backlight enable-gpios instead of using 0.
Change panel node naming from "panel-simple" to "panel".
