Samsung S3C24xx and S3C64xx machine code cleanup for v5.10

Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos.  This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.

The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform.  The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory.  However this is step forward for multiplatform or at least
to keep this code still maintainable.

This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.
