ARM: s3c64xx: allow building without board support
Most of the code for the s3c64xx platform is only used when booting with ATAGS based board files, but not when using device-tree. This tries to identify all the s3c64xx specific code that is unneeded when CONFIG_ATAGS is not set, so we can build a smaller DT-only kernel if configured that way. All board support is still left intact but now depends on the CONFIG_ATAGS symbol that users may intentionally disable. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
