aspeed/smc: Add support for DMAs
The FMC controller on the Aspeed SoCs support DMA to access the flash
modules. It can operate in a normal mode, to copy to or from the flash
module mapping window, or in a checksum calculation mode, to evaluate
the best clock settings for reads.

The model introduces two custom address spaces for DMAs: one for the
AHB window of the FMC flash devices and one for the DRAM. The latter
is populated using a "dram" link set from the machine with the RAM
container region.
