Konsta Hölttä e9d453806c gpu: nvgpu: move duplicate timer api to common
The high level API for the timer unit is the same across all OSs, so
get rid of the slight code duplication by moving the timer init
functions under a new file in common code:

- nvgpu_timeout_init_cpu_timer
- nvgpu_timeout_init_cpu_timer_sw
- nvgpu_timeout_init_retry

Much of the timer logic is also duplicated, but it is mixed between OS
specific current time retrieval. With some refactoring and addition of
an OS independent time keeping layer, that logic could also be made
shared.
