Cédric Le Goater c2da8a8b90 ast2400: add a memory controller device model
The uboot in the previous release of the SDK was using a hardcoded
value for memory size. This is not true anymore, the value is now
retrieved from the memory controller.

Below is a model for this device, only supporting unlock and
configuration. Without it, we endup running a guest with 64MB, which
is a bit low nowdays. It uses a 'silicon-rev' property and ram_size to
build a default value. Some bits should be linked to SCU strapping
registers but it seems a bit complex to add for the current need.

The model is ready for the AST2500 SOC.
