In several functions in arch/arm/mach-footbridge/netwinder-hw.c, the
value of the variable i is only used if DEBUG is defined (because
dprintk() expands to nothing if it is not defined). This causes
compilation warnings when building with W=1 if DEBUG is not defined.
Resolve this issue by only defining the variable if DEBUG is defined.
