2018-06-28bus: add bus driver for accessing Allwinner A64 DE2Icenowy Zheng1-0/+48
The "Display Engine 2.0" (usually called DE2) on the Allwinner A64 SoC is different from the ones on other Allwinner SoCs. It requires a SRAM region to be claimed, otherwise all DE2 subblocks won't be accessible. Add a bus driver for the Allwinner A64 DE2 part which claims the SRAM region when probing.
