ARM: s3c: i2c: add platform_device forward declaration

Browse source 
A recent cleanup to the mach-osiris.c file is causing build errors
because the i2c-s3c2410.h header file is included before we see
the definition for platform_device. The fix is to make the header file
more robust against inclusion from other places. While this should
normally go through the i2c tree, the bug only exists in arm-soc
at the moment, so it's easier to fix it there before it goes upstream.

Without this patch, building s3c2410_defconfig results in:

arch/arm/mach-s3c24xx/mach-osiris.c:34:0:
include/linux/platform_data/i2c-s3c2410.h:37:26: warning: 'struct platform_device' declared inside parameter list [enabled by default]
