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.

Ensure the ASPEED related options are grouped together under the RAM
option when enabling support.
This also makes some minor grammar corrections and renames options so
they present cleanly in menuconfig.
There should be no functional change to the configuration or binary.

512MbX16 (8Gb), 1GbX16 (16Gb), and 1GbX8 TwinDie (16Gb) are supported.

the aspeed ddr sdram controller needs to know if the memory chip mounted on
the board is dual x8 die or not. Or it may get the wrong size of the
memory space.
