ndelay(): switch to C function to avoid 64-bit division
We should be able to do ndelay(some_u64), but that can cause a call to
__divdi3() to be emitted because the ndelay() macros does a divide.
Fix it by switching to static inline which will force the u64 arg to be
treated as an unsigned long. udelay() takes an unsigned long arg.
