Move the ARM Samsung s3c2xx0 support files into the samsung directory, to
match other platforms.

Trim trailing whitespace...

Add support for the Samsung S3C2xx0 family of ARM SoCs written by
Andrew Turner. The kernel supports the LN2410SBC evaluation board,
and likely others. These parts (or similar ones) are in some open
hardware designs for phones.
