gpu: nvgpu: move set_timeslice to tsg

Browse Source 
Moved the following HALs from fifo to tsg
- set_timeslice
- default_timeslice_us

Renamed
- gk20a_tsg_set_timeslice -> nvgpu_tsg_set_timeslice
- min_timeslice_us -> tsg_timeslice_min_us
- max_timeslice_us -> tsg_timeslice_max_us

Scale timeslice to take into account PTIMER clock in
nvgpu_runlist_append_tsg.

Removed gk20a_channel_get_timescale_from_timeslice, and
instead moved timeout and scale computation into runlist HAL,
when building TSG entry:
- runlist.get_tsg_entry

Use ram_rl_entry_* accessors instead of hard coded values
for default and max timeslices.

Added #defines for min, max and default timeslices.
