The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>
