ARM: s3c: Kconfig.s3c24xx: Fix indentation and replace some tabs

The convention for indentation seems to be a single tab. Help text is
further indented by an additional two whitespaces. Fix the lines that
violate these rules.

While add it, replace tabs before comments with whitespaces (which seems to
be more common), add a missing trailing endif comment and squeeze multiple
empty lines.
