gpu: nvgpu: use timespec64

Browse Source 
Due to y2038 problem, where timestamps will overflow if logged in 32bit
values, upstream linux kernel has removed timespec and friends.

Correpsonding jiffies conversion functions are also obsolete. Update
the notifier timestamp setup code to comply with this.
