Move s3c24x0 header files to asm-arm/arch-s3c24x0/

This patch moves the s3c24x0 header files from include/ to
include/asm-arm/arch-s3c24x0/.

checkpatch.pl showed 2 errors and 3 warnings. The 2 errors were both due
to a non-UTF8 character in David M?ller's name:

ERROR: Invalid UTF-8, patch and commit message should be encoded in UTF-8
#489: FILE: include/asm-arm/arch-s3c24x0/s3c2410.h:3:
+ * David M?ller ELSOFT AG Switzerland. d.mueller@elsoft.ch

As David's name correctly contains a non-UTF8 character I haven't fixed
these errors.

The 3 warnings were all because of the use of 'volatile' in s3c24x0.h:

WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
#673: FILE: include/asm-arm/arch-s3c24x0/s3c24x0.h:35:
+typedef volatile u8	S3C24X0_REG8;
+typedef volatile u16	S3C24X0_REG16;
+typedef volatile u32	S3C24X0_REG32;

I'll fix these errors in another patch.

Tested by running MAKEALL for ARM8 targets and ensuring there were no new
errors or warnings.
