gpu: nvgpu: add ioctls to get current timeslice

Browse Source 
Add the following ioctls
- NVGPU_CHANNEL_IOCTL_GET_TIMESLICE for channel timeslice in us
- NVGPU_TSG_IOCTL_GET_TIMESLICE for TSG timeslice in us

If timeslice has not been set explicitly, ioctl returns the
default timeslice that will be used when programming the runlist
entry.
