[PATCH v2 6/7] arm64: allwinner: a64: add device tree node for HDMI simplefb

[Icenowy Zheng]

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.
