powerpc: Change u64/s64 to a long long integer type

Convert arch/powerpc/ over to long long based u64:

 -#ifdef __powerpc64__
 -# include <asm-generic/int-l64.h>
 -#else
 -# include <asm-generic/int-ll64.h>
 -#endif
 +#include <asm-generic/int-ll64.h>

This will avoid reoccuring spurious warnings in core kernel code that
comes when people test on their own hardware. (i.e. x86 in ~98% of the
cases) This is what x86 uses and it generally helps keep 64-bit code
32-bit clean too.

[Adjusted to not impact user mode (from paulus) - sfr]
