[PATCH v4 5/6] arm64: allwinner: a64: add simplefb for A64 SoC

[Icenowy Zheng <icenowy-h8G6r0blFSE@public.gmane.org>]

The A64 SoC features two display pipelines, one has a LCD output, the
other has a HDMI output.

Add support for simplefb for these pipelines on A64 SoC.

Signed-off-by: Icenowy Zheng <icenowy-h8G6r0blFSE@public.gmane.org>
---
Changes in v4:
- Dropped extra clocks.
- Added labels to the SimpleFB device tree nodes as boards may have
  extra regulator for display pipeline.
