Fix accidental implicit cast in HR-timer conversion
Fix the hrtimer_add_expires_ns() function. It should take a 'u64 ns' argument, but rather takes an 'unsigned long ns' argument - which might only be 32-bits. On FRV, this results in the kernel locking up because hrtimer_forward() passes the result of a 64-bit multiplication to this function, for which the compiler discards the top 32-bits - something that didn't happen when ktime_add_ns() was called directly.
