ARM: s3c: move into a common directory
s3c24xx and s3c64xx have a lot in common, but are split across three separate directories, which makes the interaction of the header files more complicated than necessary. Move all three directories into a new mach-s3c, with a minimal set of changes to each file. Signed-off-by: Arnd Bergmann <arnd@arndb.de> [krzk: Rebase, add s3c24xx and s3c64xx suffix to several files, add SPDX headers to new files, remove plat-samsung from MAINTAINERS] Co-developed-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> https://lore.kernel.org/r/20200806182059.2431-39-krzk@kernel.org
