This is not really a CONFIG since it is not intended to be set by boards.
Move it into the compiler header with other similar defines, and rename
it.

-- CONFIG_SYS_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
+- MEM_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
 		Optionally it can be defined to support 64-bit memory commands.
