[ARM] S3C24XX: dma.h should not include <mach/hardware.h>

The dma.h header does not need to include <mach/hardware.h> as there
is nothing it depends on. Remove the include and fixup the couple of
places where <mach/map.h> was not explicitly included (dragged in
via <mach/hardware.h>)

Note, we have to fix arch/arm/plat-s3c24xx/pm.c which seems to rely
on having <mach/hardware.h> included by this method.
