Konsta Holtta 72726c70b8 gpu: nvgpu: use ktime instead of jiffies in timeouts ...

Instead of the very coarse jiffies, use the more accurate monotonic
Linux ktime API for the nvgpu timeout API.

The expiration time is handled as an u64 nanosecond value to hide the
ktime_t from the public nvgpu_timeout struct. The conversion is cheap.
