Add compatible string for the Microchip's AC40T08A MIPI Display
panel.This panel uses a Himax HX8394 display controller.
The reset line is not populated and leads to driver probe issues,
thus add conditional block to narrow reset-gpio property per variant.

changes in v2:
- re-order compatible string alphabetically.
- Add conditional block to narrow reset-gpio property from required
list based on compatible string check
