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.

This patch has many checkpatch.pl warning due to the two vendor-provided sources for DDR PHY initialization.
Most of the warnings are about the camel case coding style and line length checks.
If possible, we wish to keep it as is for better vendor support in case debugging is needed.
