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.

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.
