dt-bindings: add binding for Allwinner A64 SRAM controller and SRAM C
The display engine on Allwinner A64 wants to claim the SRAM C section. Add a SRAM controller compatible for A64, and a SRAM section compatible for its SRAM C. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Chen-Yu Tsai <wens@csie.org>
