The Aspeed SMC device model use to have a 'sdram_base' property. It was removed by commit d177892d4a48 ("aspeed/smc: Remove unused "sdram-base" property") because previous changes simplified the DMA transaction model to use an offset in RAM and not the physical address. The AST2700 SoC has larger address space (64-bit) and a new register DMA DRAM Side Address High Part (0x7C) is introduced to deal with the high bits of the DMA address. To be able to compute the offset of the DMA transaction, as done on the other SoCs, we will need to know where the DRAM is mapped in the address space. Re-introduce a "dram-base" property to hold this value.
