Add a new AST2700 A2 EVB machine to model the newer A2 silicon.

The ast2700a2-evb machine is largely identical to ast2700a1-evb.
The only difference is the default DRAM size, which is increased
to 2 GB.

This change adds a dedicated ast2700a2-evb machine by copying the
existing ast2700a1-evb configuration and updating the DRAM size
accordingly.
