MGS-4123 gpu: dts: fix axi bus error on 6dl sabreauto board
meet axi bus error when setting 3G/1G user/kernel VM space layout,
it is casued by gpu with legacy mmu, which requires cma under 2GB.
in this case, 6dl cma exceed 2G with 3G/1G user /kernel VM layerout.
Reserved memory: created CMA memory pool at 0x7a000000, size 320 MiB
set gpu base-address with 256M to avoid axi bus error on 2G board.
