[PATCH v2] ARM: s3c64xx: Add missing head file

[Kefeng Wang]

The building reports warning after patch "arm: Remove unnecessary
of_platform_populate with default match table",

"arch/arm/mach-s3c64xx/common.h:28:2: warning: 'struct device_node' declared inside parameter list"

Add the missing of.h for device_node struct in common.h, and kill common.h
from arch/arm/mach-s3c64xx/mach-s3c64xx-dt.c, because no function need it.

Hi Krzysztof, 

Thanks for your points, add "Reported-by" tag in v2, and Rob can directly
pick it up if necessary.

Thanks,
Kefeng
