As the U-Boot bootloader now is also capable of initialize the HDMI on
A64 boards, add a simplefb device tree node for accessing the HDMI
framebuffer initialized by the bootloader.

Changes in v2:
- Dropped LCD SimpleFB as it's already added. LCD SimpleFB needs some
fix but the fix is present when adding DE2 CCU.
