a1ad11ce52 ram: ast2700: Add DRAM controller initialization 
Add driver for AST2700 to initialize DRAM in SPL.

This patch also refactors the Kconfig dependency of
Aspeed DRAM drivers as some of them are shared among
the file structures of RV and ARM ISAs.

5d457f8057 ram: move aspeed ram driver into drivers/ directory 
to improve the maintainability.  It is more easier to modify and add
configurations of the driver in the centralized ram driver directory.
